97220-08-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97220-08-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,2 and 0 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 97220-08:
(7*9)+(6*7)+(5*2)+(4*2)+(3*0)+(2*0)+(1*8)=131
131 % 10 = 1
So 97220-08-1 is a valid CAS Registry Number.
