7439-00-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7439-00-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,3 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7439-00:
(6*7)+(5*4)+(4*3)+(3*9)+(2*0)+(1*0)=101
101 % 10 = 1
So 7439-00-1 is a valid CAS Registry Number.
