99423-94-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99423-94-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,2 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 99423-94:
(7*9)+(6*9)+(5*4)+(4*2)+(3*3)+(2*9)+(1*4)=176
176 % 10 = 6
So 99423-94-6 is a valid CAS Registry Number.
