97531-03-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97531-03-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,5,3 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 97531-03:
(7*9)+(6*7)+(5*5)+(4*3)+(3*1)+(2*0)+(1*3)=148
148 % 10 = 8
So 97531-03-8 is a valid CAS Registry Number.
