Check Digit Verification of cas no
The CAS Registry Mumber 68873-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,8,7 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68873-21:
(7*6)+(6*8)+(5*8)+(4*7)+(3*3)+(2*2)+(1*1)=172
