Check Digit Verification of cas no
The CAS Registry Mumber 30823-51-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,8,2 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 30823-51:
(7*3)+(6*0)+(5*8)+(4*2)+(3*3)+(2*5)+(1*1)=89
89 % 10 = 9
So 30823-51-9 is a valid CAS Registry Number.
