4079-10-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4079-10-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,7 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.Calculate Digit Verification of CAS Registry Number 4079-10:
(6*4)+(5*0)+(4*7)+(3*9)+(2*1)+(1*0)=81
81 % 10 = 1
So 4079-10-1 is a valid CAS Registry Number.
