40348-04-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40348-04-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,4 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40348-04:
(7*4)+(6*0)+(5*3)+(4*4)+(3*8)+(2*0)+(1*4)=87
87 % 10 = 7
So 40348-04-7 is a valid CAS Registry Number.
