Check Digit Verification of cas no

The CAS Registry Mumber 1252577-35-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,2,5,7 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1252577-35:
(9*1)+(8*2)+(7*5)+(6*2)+(5*5)+(4*7)+(3*7)+(2*3)+(1*5)=157
157 % 10 = 7
So 1252577-35-7 is a valid CAS Registry Number.

Synthesis of 3-substituted 1-thioacyl- and 1-thiocarbamoylindoles from-substituted 2-isocyanato-β-methoxystyrenes

Fukamachi, Shuhei,Fujita, Seiki,Murahashi, Kazuya,Konishi, Hisatoshi,Kobayashi, Kazuhiro

experimental part, p. 2985 - 2989 (2010/11/04)

3-Aryl-1-thioacylindoles were prepared by treating α-aryl-2- isothiocyanato-β-methoxystyrenes with organolithiums or Grignard reagents, followed by hydriodic acid catalyzed cyclization of the resulting adducts. A one-pot synthesis of 1-thiocarbamoylindoles was achieved by hydriodic acid mediated cyclization of the corresponding thiourea intermediates, prepared from α-substituted 2-isothiocyanato-β-methoxystyrenes and secondary amines.
