Check Digit Verification of cas no
The CAS Registry Mumber 90023-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,2 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90023-17:
(7*9)+(6*0)+(5*0)+(4*2)+(3*3)+(2*1)+(1*7)=89
89 % 10 = 9
So 90023-17-9 is a valid CAS Registry Number.
