103440-00-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103440-00-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,4,4 and 0 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103440-00:
(8*1)+(7*0)+(6*3)+(5*4)+(4*4)+(3*0)+(2*0)+(1*0)=62
62 % 10 = 2
So 103440-00-2 is a valid CAS Registry Number.
