Check Digit Verification of cas no
The CAS Registry Mumber 129296-34-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,9 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129296-34:
(8*1)+(7*2)+(6*9)+(5*2)+(4*9)+(3*6)+(2*3)+(1*4)=150
150 % 10 = 0
So 129296-34-0 is a valid CAS Registry Number.
