Check Digit Verification of cas no

The CAS Registry Mumber 1259282-85-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,2,8 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1259282-85:
(9*1)+(8*2)+(7*5)+(6*9)+(5*2)+(4*8)+(3*2)+(2*8)+(1*5)=183
183 % 10 = 3
So 1259282-85-3 is a valid CAS Registry Number.

Sulfur-assisted propargyl-allenyl isomerizations and intramolecular cyclization for the synthesis of tricyclic thiophene derivatives

Xu, Guangyu,Chen, Kaixiong,Zhou, Hongwei

, p. 6240 - 6242 (2010)

A facile and efficient cyclization for the synthesis of tricyclic thiophene derivatives was developed. As a metal-free process, a result of the ready availability of the starting materials and the simple and convenient operation, the type of reaction presented here has potential utility in organic synthesis.
