97577-34-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97577-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,5,7 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 97577-34:
(7*9)+(6*7)+(5*5)+(4*7)+(3*7)+(2*3)+(1*4)=189
189 % 10 = 9
So 97577-34-9 is a valid CAS Registry Number.
