Check Digit Verification of cas no
The CAS Registry Mumber 129329-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,2 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129329-65:
(8*1)+(7*2)+(6*9)+(5*3)+(4*2)+(3*9)+(2*6)+(1*5)=143
143 % 10 = 3
So 129329-65-3 is a valid CAS Registry Number.
