97106-56-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97106-56-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,1,0 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97106-56:
(7*9)+(6*7)+(5*1)+(4*0)+(3*6)+(2*5)+(1*6)=144
144 % 10 = 4
So 97106-56-4 is a valid CAS Registry Number.
