Check Digit Verification of cas no
The CAS Registry Mumber 121673-76-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,7 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 121673-76:
(8*1)+(7*2)+(6*1)+(5*6)+(4*7)+(3*3)+(2*7)+(1*6)=115
115 % 10 = 5
So 121673-76-5 is a valid CAS Registry Number.
