Check Digit Verification of cas no

The CAS Registry Mumber 915719-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,5,7,1 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 915719-46:
(8*9)+(7*1)+(6*5)+(5*7)+(4*1)+(3*9)+(2*4)+(1*6)=189
189 % 10 = 9
So 915719-46-9 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
