Check Digit Verification of cas no

The CAS Registry Mumber 286435-30-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,6,4,3 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 286435-30:
(8*2)+(7*8)+(6*6)+(5*4)+(4*3)+(3*5)+(2*3)+(1*0)=161
161 % 10 = 1
So 286435-30-1 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.
