97234-03-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97234-03-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,3 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 97234-03:
(7*9)+(6*7)+(5*2)+(4*3)+(3*4)+(2*0)+(1*3)=142
142 % 10 = 2
So 97234-03-2 is a valid CAS Registry Number.
