494841-91-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 494841-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,4,8,4 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 494841-91:
(8*4)+(7*9)+(6*4)+(5*8)+(4*4)+(3*1)+(2*9)+(1*1)=197
197 % 10 = 7
So 494841-91-7 is a valid CAS Registry Number.
