Check Digit Verification of cas no

The CAS Registry Mumber 129610-00-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,6,1 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129610-00:
(8*1)+(7*2)+(6*9)+(5*6)+(4*1)+(3*0)+(2*0)+(1*0)=110
110 % 10 = 0
So 129610-00-0 is a valid CAS Registry Number.

7,10a-Methanocyclooctaindazoles: Diisophoranes Incorporating the Pyrazole Ring System

Kurzer, Frederick,Langer, Stanley S.

, p. 871 - 879 (2007/10/02)

Compounds of the novel 7,10a-methanocyclooctaindazole ring-system 5, 7 are obtained by the action of hydrazines on 1-chloro(or hydroxy)diisophor-2,7-en-3-ones 1-3.Their formulation agrees with their origin and their chemical and spectral characteristics.Analogous syntheses of two comparable ring-systems include the production of a substituted 7,10a-methanocyclooctabenzisoxazole 10 by a facile cyclodehydration of the oxime of diisophorone 9a, and that of the indole-analogue 13 by the action of aniline on diisophorone-1-carboxylic acid 11.
