93404-06-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93404-06-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,4,0 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 93404-06:
(7*9)+(6*3)+(5*4)+(4*0)+(3*4)+(2*0)+(1*6)=119
119 % 10 = 9
So 93404-06-9 is a valid CAS Registry Number.
