Check Digit Verification of cas no
The CAS Registry Mumber 29884-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,8,8 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 29884-49:
(7*2)+(6*9)+(5*8)+(4*8)+(3*4)+(2*4)+(1*9)=169
169 % 10 = 9
So 29884-49-9 is a valid CAS Registry Number.
