Check Digit Verification of cas no

The CAS Registry Mumber 102939-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,9,3 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 102939-75:
(8*1)+(7*0)+(6*2)+(5*9)+(4*3)+(3*9)+(2*7)+(1*5)=123
123 % 10 = 3
So 102939-75-3 is a valid CAS Registry Number.

INTRAMOLECULAR TRAPPING BY EPOXIDES OF INTERMEDIATES GENERATED BY ORGANOCUPRATE ADDITIONS TO PROPIOLATE ESTERS.

Lewis, David E.,Rigby, H. Lee

, p. 3437 - 3440 (2007/10/02)

The facility with which intramolecular trapping of the intermediates generated by conjugate addition of organocopper nucleophiles to propiolate esters may be effected by internal epoxides is critically dependent on the nature of the nucleophile.
