Check Digit Verification of cas no

The CAS Registry Mumber 1239919-65-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,9,1 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1239919-65:
(9*1)+(8*2)+(7*3)+(6*9)+(5*9)+(4*1)+(3*9)+(2*6)+(1*5)=193
193 % 10 = 3
So 1239919-65-3 is a valid CAS Registry Number.

Stereocontrol in radical cyclization: Change in rate-determining step

Hakim, Siddiki S. M. A.,Sugimura, Takashi

supporting information; experimental part, p. 3626 - 3629 (2010/10/04)

Intramolecular cyclization of an α-carbon radical of ester carrying a chiral 2,4-pentanediol tether shows low stereoselectivity when the radical carbon has an alkyl substituent, while the selectivity becomes high to give a single stereoisomer (>99% pure)
