Check Digit Verification of cas no

The CAS Registry Mumber 57193-26-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,9 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57193-26:
(7*5)+(6*7)+(5*1)+(4*9)+(3*3)+(2*2)+(1*6)=137
137 % 10 = 7
So 57193-26-7 is a valid CAS Registry Number.

Preparation of All the Possible Ring-deuteriated Benzoic Acids by Reductive Dehalogenation of the Corresponding Halogenobenzoic Acids with Raney Alloys in an Alkaline Deuterium Oxide Solution

Tashiro, Masashi,Nakayama, Kouji,Fukata, Gouki

, p. 2315 - 2318 (2007/10/02)

All the possible undeuteriated benzoic acids were prepared mainly by treatment of the corresponding bromobenzoic acid with Raney Cu-Al alloy in 10percent NaOD-D2O solution. 5>Benzoic acid was obtained from pentafluorobenzoic acid by a similar reaction.However, only 4>benzoic acid was prepared by decarboxylation of 4>phthalic acid.
