Check Digit Verification of cas no

The CAS Registry Mumber 80141-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,1,4 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80141-75:
(7*8)+(6*0)+(5*1)+(4*4)+(3*1)+(2*7)+(1*5)=99
99 % 10 = 9
So 80141-75-9 is a valid CAS Registry Number.

ETUDE DU COMPORTEMENT CHIMIQUE DE PYRANOPYRAZOLE-3(2H)-ONES VIS-A-VIS DES BASES AZOTEES. II. Reaction avec les amines aliphatiques.

Maquestiau, A.,Haverbeke, Y. van,Eynde, J. J. vanden

, p. 955 - 962 (2007/10/02)

Pyranopyrazole-3(2H)-ones easily add aliphatic amines on the 6 position: the reaction is reversible.By prolonged heating and with primary amines only, the formation of alkylaminoethylidenepyrazolidin-3,5-diones is observed.
