1273331-68-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1273331-68-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,3,3,3 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1273331-68:
(9*1)+(8*2)+(7*7)+(6*3)+(5*3)+(4*3)+(3*1)+(2*6)+(1*8)=142
142 % 10 = 2
So 1273331-68-2 is a valid CAS Registry Number.
