136289-41-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136289-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,2,8 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136289-41:
(8*1)+(7*3)+(6*6)+(5*2)+(4*8)+(3*9)+(2*4)+(1*1)=143
143 % 10 = 3
So 136289-41-3 is a valid CAS Registry Number.

Vicarious nucleophilic substitution of hydrogen in electrophilic alkenes
Makosza,Kwast
, p. 5001 - 5018 (2007/10/02)
Carbanions containing leaving groups react in the presence of base with electrophilic alkenes giving products in which vinylic hydrogen is replaced with the carbanion moiety. They are formed via addition - β-elimination pathway analogous to the vicarious
