Check Digit Verification of cas no
The CAS Registry Mumber 127649-10-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,4 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127649-10:
(8*1)+(7*2)+(6*7)+(5*6)+(4*4)+(3*9)+(2*1)+(1*0)=139
139 % 10 = 9
So 127649-10-9 is a valid CAS Registry Number.

Olefination with Sulfonyl Halides and Esters: Scope, Limitations, and Mechanistic Studies of the Hawkins Reaction

Carbanions of alkanesulfonyl halides and esters react with nonenolizable carbonyl compounds to give olefins. Mechanistic studies reveal that initial aldol-type addition of the carbanions is followed by cyclization-fragmentation to alkenes, and the leaving group on the sulfonyl moiety (RSO2X) controls carbanion stability and rate of the olefin formation.
