78474-84-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78474-84-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,4,7 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 78474-84:
(7*7)+(6*8)+(5*4)+(4*7)+(3*4)+(2*8)+(1*4)=177
177 % 10 = 7
So 78474-84-7 is a valid CAS Registry Number.
