Check Digit Verification of cas no
The CAS Registry Mumber 21211-09-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,1 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21211-09:
(7*2)+(6*1)+(5*2)+(4*1)+(3*1)+(2*0)+(1*9)=46
46 % 10 = 6
So 21211-09-6 is a valid CAS Registry Number.
