949004-66-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 949004-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,9,0,0 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 949004-66:
(8*9)+(7*4)+(6*9)+(5*0)+(4*0)+(3*4)+(2*6)+(1*6)=184
184 % 10 = 4
So 949004-66-4 is a valid CAS Registry Number.
