Check Digit Verification of cas no
The CAS Registry Mumber 138719-65-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,1 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138719-65:
(8*1)+(7*3)+(6*8)+(5*7)+(4*1)+(3*9)+(2*6)+(1*5)=160
160 % 10 = 0
So 138719-65-0 is a valid CAS Registry Number.
