99499-63-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99499-63-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,9 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99499-63:
(7*9)+(6*9)+(5*4)+(4*9)+(3*9)+(2*6)+(1*3)=215
215 % 10 = 5
So 99499-63-5 is a valid CAS Registry Number.
