Check Digit Verification of cas no

The CAS Registry Mumber 1112262-71-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,2,2,6 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1112262-71:
(9*1)+(8*1)+(7*1)+(6*2)+(5*2)+(4*6)+(3*2)+(2*7)+(1*1)=91
91 % 10 = 1
So 1112262-71-1 is a valid CAS Registry Number.

Synthetic studies on statins. Part 1: A short and cyanide-free synthesis of atorvastatin calcium via an enantioselective aldol strategy

Hu, Lemeng,Xiong, Fangjun,Chen, Xiaofei,Chen, Wenxue,He, Qiuqin,Chen, Fener

, p. 207 - 211 (2013/04/10)

A short and cyanide-free enantioselective synthesis of atorvastatin calcium has been achieved starting from a commercially available highly substituted 1,4-diketone in an overall yield of 40%. The key step in this approach is the asymmetric aldol reaction of an aldehyde with diketene in the presence of Ti(O-i-Pr)4-Schiff base complex to create the (5R)-stereochemistry of atorvastatin calcium.
