66274-77-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66274-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,2,7 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 66274-77:
(7*6)+(6*6)+(5*2)+(4*7)+(3*4)+(2*7)+(1*7)=149
149 % 10 = 9
So 66274-77-9 is a valid CAS Registry Number.
