Check Digit Verification of cas no
The CAS Registry Mumber 921-09-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,2 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 921-09:
(5*9)+(4*2)+(3*1)+(2*0)+(1*9)=65
65 % 10 = 5
So 921-09-5 is a valid CAS Registry Number.
