97586-33-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97586-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,5,8 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 97586-33:
(7*9)+(6*7)+(5*5)+(4*8)+(3*6)+(2*3)+(1*3)=189
189 % 10 = 9
So 97586-33-9 is a valid CAS Registry Number.
