Check Digit Verification of cas no
The CAS Registry Mumber 130879-62-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,7 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 130879-62:
(8*1)+(7*3)+(6*0)+(5*8)+(4*7)+(3*9)+(2*6)+(1*2)=138
138 % 10 = 8
So 130879-62-8 is a valid CAS Registry Number.
