94167-28-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94167-28-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,1,6 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 94167-28:
(7*9)+(6*4)+(5*1)+(4*6)+(3*7)+(2*2)+(1*8)=149
149 % 10 = 9
So 94167-28-9 is a valid CAS Registry Number.
