Check Digit Verification of cas no
The CAS Registry Mumber 142041-29-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,0,4 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 142041-29:
(8*1)+(7*4)+(6*2)+(5*0)+(4*4)+(3*1)+(2*2)+(1*9)=80
80 % 10 = 0
So 142041-29-0 is a valid CAS Registry Number.
