Check Digit Verification of cas no

The CAS Registry Mumber 18889-01-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,8 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18889-01:
(7*1)+(6*8)+(5*8)+(4*8)+(3*9)+(2*0)+(1*1)=155
155 % 10 = 5
So 18889-01-5 is a valid CAS Registry Number.

Efficient Transformation of Trithio- and Triseleno-orthoesters into Ketene Dithio- and Diseleno-acetals

Nsunda, K. M.,Hevesi, L.

, p. 1000 - 1001 (1985)

Sequential treatment of trithio- and triseleno-orthoesters with a Lewis acid followed by a base leads to ketene dithio- and diseleno-acetals in good yield; SnCl4 or TiCl4 and (i-Pr)2EtN or Et3N are the most efficient reagents.

Copper(I) bromide - dimethyl sulfide complex - An alternative to copper(I) triflate for removal of the thiophenoxide group

Cohen, Theodore,Shook, Craig,Thiruvazhi, Mohan

, p. 6041 - 6042 (1994)

Commercially available copper(I) bromide - dimethyl sulfide complex is comparable to the far more expensive copper(I) triflate in assisting the removal of the thiophenoxide group from certain substrates.

ELIMINATION OF THIOPHENOL FROM PHENYL ORTHOTHIOESTERS IN THE MASS SPECTROMETER AND NOVEL REARRANGEMENT OF KETENE THIOACETALS UPON ELECTRON IMPACT

El-Khawaga, Ahmed M.,El-Zohry, Maher F.

, p. 179 - 183 (2007/10/02)

The mass spectra of four selected phenyl orthothioesters (1-4) have been measured.The obtained spectra revealed the conversion of the compounds (1-4) into ketene thioacetals (5-8) via the elimination of thiophenol in the mass spectrometer.The thermal natu
