Check Digit Verification of cas no
The CAS Registry Mumber 120017-13-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,0,1 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 120017-13:
(8*1)+(7*2)+(6*0)+(5*0)+(4*1)+(3*7)+(2*1)+(1*3)=52
52 % 10 = 2
