108440-51-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108440-51-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,4,4 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 108440-51:
(8*1)+(7*0)+(6*8)+(5*4)+(4*4)+(3*0)+(2*5)+(1*1)=103
103 % 10 = 3
So 108440-51-3 is a valid CAS Registry Number.
