Check Digit Verification of cas no
The CAS Registry Mumber 74017-86-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,1 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74017-86:
(7*7)+(6*4)+(5*0)+(4*1)+(3*7)+(2*8)+(1*6)=120
120 % 10 = 0
