Check Digit Verification of cas no

The CAS Registry Mumber 1228811-99-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,8,1 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1228811-99:
(9*1)+(8*2)+(7*2)+(6*8)+(5*8)+(4*1)+(3*1)+(2*9)+(1*9)=161
161 % 10 = 1
So 1228811-99-1 is a valid CAS Registry Number.

Organocatalytic kinetic resolution via intramolecular aldol reactions: Enantioselective synthesis of both enantiomers of chiral cyclohexenones

Chen, Liujuan,Luo, Sanzhong,Li, Jiuyuan,Li, Xin,Cheng, Jin-Pei

experimental part, p. 2627 - 2632 (2010/07/05)

Kinetic resolution of 6-aryl-2,6-hexanediones was achieved with chiral secondary amine catalyzed intramolecular aldolization. The current kinetic resolution protocol enables the synthesis of both enantiomers of cyclohexenones with moderate to good enantioselectivity. The Royal Society of Chemistry 2010.
