97549-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97549-91-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,5,4 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 97549-91:
(7*9)+(6*7)+(5*5)+(4*4)+(3*9)+(2*9)+(1*1)=192
192 % 10 = 2
So 97549-91-2 is a valid CAS Registry Number.
