Check Digit Verification of cas no
The CAS Registry Mumber 139979-81-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,7 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139979-81:
(8*1)+(7*3)+(6*9)+(5*9)+(4*7)+(3*9)+(2*8)+(1*1)=200
200 % 10 = 0
So 139979-81-0 is a valid CAS Registry Number.
