The CAS Registry Mumber 74864-08-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,6 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74864-08:
(7*7)+(6*4)+(5*8)+(4*6)+(3*4)+(2*0)+(1*8)=157
157 % 10 = 7
So 74864-08-7 is a valid CAS Registry Number.

ADDITIONS REGIOSELECTIVES D'IMINES ET D'HYDRAZONES METALLEES AUX α-ENONES

Gorrichon-Guigon, L.,Hammerer, S.

, p. 631 - 640 (1980)

The behavior of metallated imines and hydrazones toward α,β-unsaturated ketones was studied, using different reaction times and temperatures.Dissociation of the functional group (imine or hydrazone) in the adducts and regioselectivity in their condensation reactions are discussed.The first example of reversible addition to the carbonyl group of an enone is demonstrated for the reaction between trans chalcone and (1-)*Li(1+).
