Check Digit Verification of cas no

The CAS Registry Mumber 215667-88-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,6,6 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 215667-88:
(8*2)+(7*1)+(6*5)+(5*6)+(4*6)+(3*7)+(2*8)+(1*8)=152
152 % 10 = 2
So 215667-88-2 is a valid CAS Registry Number.

New efficient nickel-catalyzed cross-coupling reaction between two Csp3 centers

Giovannini,Strudemann,Devasagayaraj,Dussin,Knochel

, p. 3544 - 3553 (2007/10/03)

The presence of a remote unsaturation (double bond, carbonyl group, cyano group) in an alkyl halide facilitates its cross-coupling reaction with various diorganozincs in the presence of Ni(acac)2 (7.5-10 mol % in THF/NMP mixtures). These results were used to develop a new general cross-coupling reaction between functionalized diorganozincs and alkyl iodides using m- or p-trifluoromethylstyrene as a reaction promotor and Ni(acac)2 as a catalyst (7.5-10 mol %; -35 °C, 5-10 h) leading to a broad range of polyfunctional cross-coupling products.
