403790-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 403790-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,7,9 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 403790-44:
(8*4)+(7*0)+(6*3)+(5*7)+(4*9)+(3*0)+(2*4)+(1*4)=133
133 % 10 = 3
So 403790-44-3 is a valid CAS Registry Number.
