Check Digit Verification of cas no
The CAS Registry Mumber 74392-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,9 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74392-89:
(7*7)+(6*4)+(5*3)+(4*9)+(3*2)+(2*8)+(1*9)=155
155 % 10 = 5
So 74392-89-5 is a valid CAS Registry Number.
