99053-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99053-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,0,5 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99053-03:
(7*9)+(6*9)+(5*0)+(4*5)+(3*3)+(2*0)+(1*3)=149
149 % 10 = 9
So 99053-03-9 is a valid CAS Registry Number.
