402505-34-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 402505-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,2,5,0 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 402505-34:
(8*4)+(7*0)+(6*2)+(5*5)+(4*0)+(3*5)+(2*3)+(1*4)=94
94 % 10 = 4
So 402505-34-4 is a valid CAS Registry Number.
