Check Digit Verification of cas no
The CAS Registry Mumber 200000-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,0,0 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 200000-21:
(8*2)+(7*0)+(6*0)+(5*0)+(4*0)+(3*0)+(2*2)+(1*1)=21
21 % 10 = 1
So 200000-21-1 is a valid CAS Registry Number.
