97222-21-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97222-21-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,2 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 97222-21:
(7*9)+(6*7)+(5*2)+(4*2)+(3*2)+(2*2)+(1*1)=134
134 % 10 = 4
So 97222-21-4 is a valid CAS Registry Number.
