Check Digit Verification of cas no
The CAS Registry Mumber 58819-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,8,1 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 58819-71:
(7*5)+(6*8)+(5*8)+(4*1)+(3*9)+(2*7)+(1*1)=169
169 % 10 = 9
So 58819-71-9 is a valid CAS Registry Number.
