Check Digit Verification of cas no

The CAS Registry Mumber 1258431-75-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,4,3 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1258431-75:
(9*1)+(8*2)+(7*5)+(6*8)+(5*4)+(4*3)+(3*1)+(2*7)+(1*5)=162
162 % 10 = 2
So 1258431-75-2 is a valid CAS Registry Number.

Synthesis and reactions with N-nucleophiles of 1-(thien-2-yl)- and 1-(4-hydroxyphenyl)-3,4,4-trichloro-3-buten-1-ones

Potkin,Petkevich,Kurman

, p. 1305 - 1312 (2010)

Acylation of thiophene and phenol with 3,4,4-trichloro-3-butenoyl chloride afforded the corresponding 1-(thien-2-yl)- and 1-(4-hydroxyphenyl)-3,4,4- trichloro-3-buten-1-ones, whose reaction with amines led to the formation of 3-amino-1-(thien-2-yl, 4-hydr
