138982-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138982-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,8 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138982-99:
(8*1)+(7*3)+(6*8)+(5*9)+(4*8)+(3*2)+(2*9)+(1*9)=187
187 % 10 = 7
So 138982-99-7 is a valid CAS Registry Number.

ASYMMETRIC AMPLIFICATION IN NICKEL-CATALYZED CONJUGATE ADDITION TO CHALCONE
Bolm, Carsten
, p. 701 - 704 (1991)
Nickel complexes with optically active pyridine ligands catalyze the conjugate addition of diethyl zinc to chalcone.This catalytic alkylation gives products with ee's of up to 86percent.Strong asymmetric amplification has been observed using ligands of lo
