291273-32-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 291273-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,1,2,7 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 291273-32:
(8*2)+(7*9)+(6*1)+(5*2)+(4*7)+(3*3)+(2*3)+(1*2)=140
140 % 10 = 0
So 291273-32-0 is a valid CAS Registry Number.
