40048-34-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40048-34-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,0,4 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40048-34:
(7*4)+(6*0)+(5*0)+(4*4)+(3*8)+(2*3)+(1*4)=78
78 % 10 = 8
So 40048-34-8 is a valid CAS Registry Number.
