Check Digit Verification of cas no
The CAS Registry Mumber 139756-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,5 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139756-31:
(8*1)+(7*3)+(6*9)+(5*7)+(4*5)+(3*6)+(2*3)+(1*1)=163
163 % 10 = 3
So 139756-31-3 is a valid CAS Registry Number.
