Check Digit Verification of cas no
The CAS Registry Mumber 21282-97-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,8 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21282-97:
(7*2)+(6*1)+(5*2)+(4*8)+(3*2)+(2*9)+(1*7)=93
93 % 10 = 3
So 21282-97-3 is a valid CAS Registry Number.
