Check Digit Verification of cas no
The CAS Registry Mumber 138690-89-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,9 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138690-89:
(8*1)+(7*3)+(6*8)+(5*6)+(4*9)+(3*0)+(2*8)+(1*9)=168
168 % 10 = 8
So 138690-89-8 is a valid CAS Registry Number.
