Check Digit Verification of cas no
The CAS Registry Mumber 400820-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,0,8,2 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 400820-21:
(8*4)+(7*0)+(6*0)+(5*8)+(4*2)+(3*0)+(2*2)+(1*1)=85
85 % 10 = 5
So 400820-21-5 is a valid CAS Registry Number.
