99072-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99072-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,0,7 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99072-20:
(7*9)+(6*9)+(5*0)+(4*7)+(3*2)+(2*2)+(1*0)=155
155 % 10 = 5
So 99072-20-5 is a valid CAS Registry Number.
