Check Digit Verification of cas no

The CAS Registry Mumber 54193-79-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,1,9 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 54193-79:
(7*5)+(6*4)+(5*1)+(4*9)+(3*3)+(2*7)+(1*9)=132
132 % 10 = 2
So 54193-79-2 is a valid CAS Registry Number.

Synthesis of isothiochromenes and 1,3-dihydrobenzo[c]thiophenes by iodine- and hydrobromic acid-mediated cyclizations of o-[(tert-butylsulfanyl)methyl)]styrenes

Kobayashi, Kazuhiro,Ueyama, Takuma,Horiuchi, Mai

, p. 2065 - 2079 (2017)

Methods for the syntheses of 4-substituted isothiochromenes and 1,1-disubstituted 1,3-dihydrobenzo[c]thiophenes have been developed. Thus, treatment of α-substituted o-[(tert-butylsulfanyl)methyl]styrenes, derived from α-substituted o-bromostyrenes using
