97988-91-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97988-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,9,8 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 97988-91:
(7*9)+(6*7)+(5*9)+(4*8)+(3*8)+(2*9)+(1*1)=225
225 % 10 = 5
So 97988-91-5 is a valid CAS Registry Number.
