Check Digit Verification of cas no

The CAS Registry Mumber 1253396-21-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,3,9 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1253396-21:
(9*1)+(8*2)+(7*5)+(6*3)+(5*3)+(4*9)+(3*6)+(2*2)+(1*1)=152
152 % 10 = 2
So 1253396-21-2 is a valid CAS Registry Number.

Synthesis of 3-substituted 3H-indol-3-ols by the reaction of 2-isocyanophenyl ketones with Grignard reagents

Kobayashi, Kazuhiro,Okamura, Yuta,Fukamachi, Shuhei,Konishi, Hisatoshi

experimental part, p. 7961 - 7964 (2010/10/19)

A facile method for the synthesis of 3-substituted 3H-indol-3-ols has been developed. Thus, 2-isocyanophenyl ketones are allowed to react with various Grignard reagents to give the corresponding desired indolol derivatives in generally fair to good yields. The formation of 3-aryl-2,3-dimethylindolin-3-ols by the reaction of 2-isocyanobenzophenones with 2 M amounts of methylmagnesium bromide is also reported.
