Check Digit Verification of cas no

The CAS Registry Mumber 170951-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,9,5 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 170951-31:
(8*1)+(7*7)+(6*0)+(5*9)+(4*5)+(3*1)+(2*3)+(1*1)=132
132 % 10 = 2
So 170951-31-2 is a valid CAS Registry Number.

Products of the Condensation Reaction of 2-(4-Halogenobenzoyl)-benzoic Acids with m-Cresol

Gronowska, J.,Kalinowska, A.

, p. 881 - 886 (2007/10/02)

The preparation and structural elucidation of new 3,3-diarylphthalides from m-cresol and 2-(4-chlorobenzoyl)benzoic acid, and from m-cresol and 2-(4-bromobenzoyl)benzoic acid were described.The optimal conditions for the separation of the mixtures of isomeric products were also reported.The direction of cyclization of corresponding derivatives of 2-benzhydrylbenzoic acid to 9-acetoxy-10-arylanthracenes were elucidated.Key words: 3,3-diarylphthalides, ε-lactone, 9-acetoxy-10-arylanthracene
