Check Digit Verification of cas no
The CAS Registry Mumber 121501-64-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,0 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121501-64:
(8*1)+(7*2)+(6*1)+(5*5)+(4*0)+(3*1)+(2*6)+(1*4)=72
72 % 10 = 2
