Check Digit Verification of cas no

The CAS Registry Mumber 1387601-49-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,7,6,0 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1387601-49:
(9*1)+(8*3)+(7*8)+(6*7)+(5*6)+(4*0)+(3*1)+(2*4)+(1*9)=181
181 % 10 = 1
So 1387601-49-1 is a valid CAS Registry Number.

Organocatalytic asymmetric synthesis of 1,2,4-trisubstituted azetidines by reductive cyclization of Aza-Michael adducts of enones

Kapoor, Ritu,Chawla, Ruchi,Singh, Santosh,Yadav, Lal Dhar S.

, p. 1321 - 1326 (2012/06/30)

An efficient and highly enantioselective organocatalytic aza-Michael addition of N-substituted phosphoramidates to enones generates aza-Michael adducts which undergo intramolecular reductive cyclization with (R)-alpine borane to afford 1,2,4-trisubstituted azetidines in a one-pot procedure. These optically active products are obtained in good to high yields (67-93%) with excellent stereocontrol (78-96% ee) from a vast variety of enones. Georg Thieme Verlag Stuttgart · New York.
