99552-09-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99552-09-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,5,5 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 99552-09:
(7*9)+(6*9)+(5*5)+(4*5)+(3*2)+(2*0)+(1*9)=177
177 % 10 = 7
So 99552-09-7 is a valid CAS Registry Number.
