Check Digit Verification of cas no

The CAS Registry Mumber 1286199-49-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,1,9 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1286199-49:
(9*1)+(8*2)+(7*8)+(6*6)+(5*1)+(4*9)+(3*9)+(2*4)+(1*9)=202
202 % 10 = 2
So 1286199-49-2 is a valid CAS Registry Number.

Preparation of meso-silylporphyrins via nickel-catalyzed coupling of meso-brominated Ni(II) porphyrins with silylzinc reagents

Hayashi, Satoshi,Endo, Taiga,Takanami, Toshikatsu

, p. 1082 - 1098 (2019/07/31)

– In this paper, we developed a technique for the nickel-catalyzed coupling of meso-brominated Ni(II) porphyrins with silylzinc reagents in order to prepare meso-silyl-substituted Ni(II) porphyrins. Porphyrin silylation occurs under mild conditions and ex
