Check Digit Verification of cas no
The CAS Registry Mumber 100005-21-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,0,0 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 100005-21:
(8*1)+(7*0)+(6*0)+(5*0)+(4*0)+(3*5)+(2*2)+(1*1)=28
28 % 10 = 8
So 100005-21-8 is a valid CAS Registry Number.
