Check Digit Verification of cas no
The CAS Registry Mumber 291282-23-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,1,2,8 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 291282-23:
(8*2)+(7*9)+(6*1)+(5*2)+(4*8)+(3*2)+(2*2)+(1*3)=140
140 % 10 = 0
So 291282-23-0 is a valid CAS Registry Number.
