Check Digit Verification of cas no
The CAS Registry Mumber 680-05-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 680-05:
(5*6)+(4*8)+(3*0)+(2*0)+(1*5)=67
67 % 10 = 7
So 680-05-7 is a valid CAS Registry Number.
