7Check Digit Verification of cas no
The CAS Registry Mumber 12269-95-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,6 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.Calculate Digit Verification of CAS Registry Number 12269-95:
(7*1)+(6*2)+(5*2)+(4*6)+(3*9)+(2*9)+(1*5)=103
103 % 10 = 3
So 12269-95-3 is a valid CAS Registry Number.
