Check Digit Verification of cas no
The CAS Registry Mumber 4425-95-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,2 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4425-95:
(6*4)+(5*4)+(4*2)+(3*5)+(2*9)+(1*5)=90
90 % 10 = 0
So 4425-95-0 is a valid CAS Registry Number.

Example 5, (2008/06/13)
Carboxylic acid compounds, each of which has an indene skeleton and represented by the following formula (2) or a fluorene skeleton and represented by the following formula (3), are each prepared by reacting an unsaturated carboxylic acid compound represented by the following formula (1) with indene or fluorene in the presence of a strong base catalyst: wherein R1, R2, R3 and R4 each independently represents an atom or group selected from a hydrogen atom, an alkyl group, an aryl group or a carboxyl group, with the proviso that at least one of R3 and R4 contains a carboxyl group or a salt thereof or a carboxylic ester group.
