403704-98-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 403704-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,7,0 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 403704-98:
(8*4)+(7*0)+(6*3)+(5*7)+(4*0)+(3*4)+(2*9)+(1*8)=123
123 % 10 = 3
So 403704-98-3 is a valid CAS Registry Number.
