Check Digit Verification of cas no
The CAS Registry Mumber 58597-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,5,9 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 58597-20:
(7*5)+(6*8)+(5*5)+(4*9)+(3*7)+(2*2)+(1*0)=169
169 % 10 = 9
So 58597-20-9 is a valid CAS Registry Number.
