Check Digit Verification of cas no
The CAS Registry Mumber 129991-09-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,9,9 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129991-09:
(8*1)+(7*2)+(6*9)+(5*9)+(4*9)+(3*1)+(2*0)+(1*9)=169
169 % 10 = 9
So 129991-09-9 is a valid CAS Registry Number.
