Check Digit Verification of cas no
The CAS Registry Mumber 129409-81-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,0 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129409-81:
(8*1)+(7*2)+(6*9)+(5*4)+(4*0)+(3*9)+(2*8)+(1*1)=140
140 % 10 = 0
So 129409-81-0 is a valid CAS Registry Number.
