Check Digit Verification of cas no
The CAS Registry Mumber 74919-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,1 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74919-04:
(7*7)+(6*4)+(5*9)+(4*1)+(3*9)+(2*0)+(1*4)=153
153 % 10 = 3
