Check Digit Verification of cas no
The CAS Registry Mumber 67878-77-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,8,7 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 67878-77:
(7*6)+(6*7)+(5*8)+(4*7)+(3*8)+(2*7)+(1*7)=197
197 % 10 = 7
So 67878-77-7 is a valid CAS Registry Number.
