99997-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99997-42-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,9 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99997-42:
(7*9)+(6*9)+(5*9)+(4*9)+(3*7)+(2*4)+(1*2)=229
229 % 10 = 9
So 99997-42-9 is a valid CAS Registry Number.
