874149-44-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 874149-44-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,1,4 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 874149-44:
(8*8)+(7*7)+(6*4)+(5*1)+(4*4)+(3*9)+(2*4)+(1*4)=197
197 % 10 = 7
So 874149-44-7 is a valid CAS Registry Number.
