403832-21-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 403832-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,8,3 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 403832-21:
(8*4)+(7*0)+(6*3)+(5*8)+(4*3)+(3*2)+(2*2)+(1*1)=113
113 % 10 = 3
So 403832-21-3 is a valid CAS Registry Number.
