Check Digit Verification of cas no
The CAS Registry Mumber 21921-54-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,2 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21921-54:
(7*2)+(6*1)+(5*9)+(4*2)+(3*1)+(2*5)+(1*4)=90
90 % 10 = 0
So 21921-54-0 is a valid CAS Registry Number.
