Check Digit Verification of cas no
The CAS Registry Mumber 21991-08-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,9 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21991-08:
(7*2)+(6*1)+(5*9)+(4*9)+(3*1)+(2*0)+(1*8)=112
112 % 10 = 2
So 21991-08-2 is a valid CAS Registry Number.
