40748-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40748-68-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,7,4 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40748-68:
(7*4)+(6*0)+(5*7)+(4*4)+(3*8)+(2*6)+(1*8)=123
123 % 10 = 3
So 40748-68-3 is a valid CAS Registry Number.
