946408-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 946408-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,6,4,0 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 946408-40:
(8*9)+(7*4)+(6*6)+(5*4)+(4*0)+(3*8)+(2*4)+(1*0)=188
188 % 10 = 8
So 946408-40-8 is a valid CAS Registry Number.
