Check Digit Verification of cas no
The CAS Registry Mumber 28211-77-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,1 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28211-77:
(7*2)+(6*8)+(5*2)+(4*1)+(3*1)+(2*7)+(1*7)=100
100 % 10 = 0
So 28211-77-0 is a valid CAS Registry Number.
