Check Digit Verification of cas no

The CAS Registry Mumber 17051-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,0,5 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17051-28:
(7*1)+(6*7)+(5*0)+(4*5)+(3*1)+(2*2)+(1*8)=84
84 % 10 = 4
So 17051-28-4 is a valid CAS Registry Number.

Indium triflate: A mild and efficient Lewis acid catalyst for O-H insertion reactions of α-diazo ketones

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

, p. 3133 - 3136 (2007/10/03)

Facile O-H insertion reactions of α-diazo ketones with aliphatic/aromatic alcohols or benzenethiol have been developed in the presence of indium triflate as a catalyst. These reactions provided good yields of α-alkoxy ketones. A comparative study with other Lewis acids establishes the reactivity of indium triflate in O-H insertion reactions of α-diazo ketones.

α-METHOXY KETONES BY THE REACTION OF TRIMETHYLSILYL ENOL ETHERS WITH LEAD TETRAACETATE IN METHANOL

Moriarty, Robert M.,Prakash, Indra,Penmasta, Raju

, p. 709 - 714 (2007/10/02)

Trimethylsilyl enol ethers of acetophenone, 2-acetylthiophene and 2-acetylfuran react with lead tetraacetate in methanol at room temperature to give the α-methoxy ketones in good yields.
