Check Digit Verification of cas no
The CAS Registry Mumber 82745-50-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,4 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 82745-50:
(7*8)+(6*2)+(5*7)+(4*4)+(3*5)+(2*5)+(1*0)=144
144 % 10 = 4
