Check Digit Verification of cas no

The CAS Registry Mumber 1514785-62-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,1,4,7,8 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1514785-62:
(9*1)+(8*5)+(7*1)+(6*4)+(5*7)+(4*8)+(3*5)+(2*6)+(1*2)=176
176 % 10 = 6
So 1514785-62-6 is a valid CAS Registry Number.

METALPORPHYRIN COMPLEX, PREPARATION METHOD THEREFOR AND METHOD FOR PREPARING POLYCARBONATE

-

Paragraph 0127-0129, (2016/08/07)

The present invention provides a metalporphyrin complex having structure represented by formula (I), wherein R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are independently selected from one of hydrogen, halogen, aliphatic group, substituted heteroaliphatic group, aryl and substituted heteroaryl; n is 1-6; L is quaternary ammonium functional group or quaternary phosphonium functional group; M is a metal element; and X is one of halogen, —NO3, BF4—, —CN, p-methyl benzoate, o-nitrophenol oxygen anion, 2,4-dinitrophenol oxygen anion, 2,4,6-trinitrophenol oxygen anion, 3,5-dichlorophenol oxygen anion and pentafluorophenol oxygen anion. The metalporphyrin complex provided in the present invention has two quaternary ammonium functional groups or two quaternary phosphonium functional groups, and compared with the prior art, the metalporphyrin complex shows higher catalytic activity in catalyzing polymerization reaction of carbon dioxide and an epoxide.
