Check Digit Verification of cas no
The CAS Registry Mumber 121030-13-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,3 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121030-13:
(8*1)+(7*2)+(6*1)+(5*0)+(4*3)+(3*0)+(2*1)+(1*3)=45
45 % 10 = 5
So 121030-13-5 is a valid CAS Registry Number.
