Check Digit Verification of cas no
The CAS Registry Mumber 74402-23-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,0 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74402-23:
(7*7)+(6*4)+(5*4)+(4*0)+(3*2)+(2*2)+(1*3)=106
106 % 10 = 6
