Check Digit Verification of cas no
The CAS Registry Mumber 21309-11-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,0 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21309-11:
(7*2)+(6*1)+(5*3)+(4*0)+(3*9)+(2*1)+(1*1)=65
65 % 10 = 5
So 21309-11-5 is a valid CAS Registry Number.
