Check Digit Verification of cas no

The CAS Registry Mumber 1257314-59-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,3,1 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1257314-59:
(9*1)+(8*2)+(7*5)+(6*7)+(5*3)+(4*1)+(3*4)+(2*5)+(1*9)=152
152 % 10 = 2
So 1257314-59-2 is a valid CAS Registry Number.

Bidentate P, N-P ligand for nickel-catalyzed cross-coupling of aryl or benzyl chlorides with ArMgX

Ghosh, Raju,Sarkar, Amitabha

experimental part, p. 8283 - 8286 (2011/03/19)

A cross-coupling reaction of a variety of aryl, heteroaryl, and benzyl chlorides with ArMgX is catalyzed by 2 mol % of a nickel-phosphine complex prepared in situ from an equimolar amount of Ni(CH3CN) 2Cl2 and ligand (L2) to yield products in excellent yield in THF at room temperature. This new bidentate ligand (L2) is stable in air and forms a stable complex upon reaction with Ni(CH3CN) 2Cl2. Structures of the ligand and the complex were confirmed by single-crystal X-ray diffraction.
