Check Digit Verification of cas no
The CAS Registry Mumber 31639-15-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,6,3 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 31639-15:
(7*3)+(6*1)+(5*6)+(4*3)+(3*9)+(2*1)+(1*5)=103
103 % 10 = 3
So 31639-15-3 is a valid CAS Registry Number.
