131140-06-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131140-06-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,4 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 131140-06:
(8*1)+(7*3)+(6*1)+(5*1)+(4*4)+(3*0)+(2*0)+(1*6)=62
62 % 10 = 2
So 131140-06-2 is a valid CAS Registry Number.

Chiral alcohol-induced diastereoselective conjugate addition and cyclization
Fang, Chenglin,Suemune, Hiroshi,Sakai, Kiyoshi
, p. 4751 - 4754 (2007/10/02)
Conjugate addition of organocuprate reagents to α,β-unsaturated esters of chiral trans-cyclohexanediol proceeded diastereoselectively, and the intramolecular trapping of the generated enolate also afforded asymmetric cyclization products.
