403503-67-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 403503-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,3,5,0 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 403503-67:
(8*4)+(7*0)+(6*3)+(5*5)+(4*0)+(3*3)+(2*6)+(1*7)=103
103 % 10 = 3
So 403503-67-3 is a valid CAS Registry Number.
