Check Digit Verification of cas no
The CAS Registry Mumber 31639-14-2 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 4 respectively.
Calculate Digit Verification of CAS Registry Number 31639-14:
(7*3)+(6*1)+(5*6)+(4*3)+(3*9)+(2*1)+(1*4)=102
102 % 10 = 2
So 31639-14-2 is a valid CAS Registry Number.
