93517-71-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93517-71-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,5,1 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 93517-71:
(7*9)+(6*3)+(5*5)+(4*1)+(3*7)+(2*7)+(1*1)=146
146 % 10 = 6
So 93517-71-6 is a valid CAS Registry Number.
