Check Digit Verification of cas no

The CAS Registry Mumber 177-16-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,7 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 177-16:
(5*1)+(4*7)+(3*7)+(2*1)+(1*6)=62
62 % 10 = 2
So 177-16-2 is a valid CAS Registry Number.

Indium triflate: A mild Lewis acid catalyst for thioacetalization and transthioacetalization

Muthusamy, Sengodagounder,Arulananda Babu, Srinivasarao,Gunanathan, Chidambaram

, p. 7897 - 7901 (2002)

Protection of a variety of carbonyl compounds as thioacetals using indium triflate, a mild Lewis acid catalyst, was achieved at ambient temperature in very good yield. Transthioacetalization of oxyacetals into thioacetals was also achieved in an excellent

Highly efficient dithioacetalization of carbonyl compounds catalyzed with iodine supported on neutral alumina

Deka, Nabajyoti,Sarma, Jadab C.

, p. 794 - 795 (2001)

Aldehydes and ketones are protected as their corresponding dithioacetals with ethane-1,2-dithiol in the presence of a catalytic amount of iodine supported on neutral alumina surface. This is a high yielding method of carbonyl group protection under mild,

Thioacetalization of aldehydes and ketones in SDS micelles

Bahrami, Kiumars,Khodaei, Mohammad Mehdi,Tajik, Maryam,Soheilizad, Mehdi

, p. 397 - 403 (2011)

Aromatic aldehydes have been successfully converted into their corresponding dithioacetal, dithiolane and dithiane derivatives in excellent yields with thiol (benzyl thiol and thiophenol), 1,2-ethanedithiol and 1,3-propanedithiol using trichloroacetic acid in sodium dodecyl sulfate micelles. The same procedure is applicable to ketones, but they need more time to be converted into their thioacetals. Image Presented.

Facile protection of carbonyl compounds as oxathiolanes and thioacetals promoted by PEG1000-based dicationic acidic ionic liquid as chemoselective and recyclable catalyst

Ren, Yi-Ming,Shao, Juan-Juan,Wu, Zhi-Chuan,Zhang, Shuai,Tao, Ting-Xian

, p. 392 - 394 (2014/06/09)

Efficient oxathioacetalization and thioacetalization of carbonyl compounds have been achieved in high yields employing PEG1000-based dicationic acidic ionic liquid as a catalyst. The PEG ionic liquid and toluene have the advantages of both homo

Silica-supported phosphorus pentoxide: A reusable catalyst for S,S-acetalization of carbonyl groups under ambient conditions

Shaterian, Hamid Reza,Azizi, Kobra,Fahimi, Nafiseh

experimental part, p. 85 - 91 (2012/01/06)

Phosphorus pentoxide supported on silica gel (P2O 5/SiO2) efficiently acts as a highly active and reusable catalyst for cyclic and non-cyclic S,S-acetalization of a variety of carbonyl compounds under mild, solvent-free an
