Check Digit Verification of cas no
The CAS Registry Mumber 99017-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,0,1 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99017-20:
(7*9)+(6*9)+(5*0)+(4*1)+(3*7)+(2*2)+(1*0)=146
146 % 10 = 6
