99367-56-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99367-56-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,6 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99367-56:
(7*9)+(6*9)+(5*3)+(4*6)+(3*7)+(2*5)+(1*6)=193
193 % 10 = 3
So 99367-56-3 is a valid CAS Registry Number.
