Check Digit Verification of cas no
The CAS Registry Mumber 23912-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,1 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 23912-28:
(7*2)+(6*3)+(5*9)+(4*1)+(3*2)+(2*2)+(1*8)=99
