97985-98-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97985-98-3 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 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 97985-98:
(7*9)+(6*7)+(5*9)+(4*8)+(3*5)+(2*9)+(1*8)=223
223 % 10 = 3
So 97985-98-3 is a valid CAS Registry Number.
