7439-49-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7439-49-8 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, 4 and 9 respectively.Calculate Digit Verification of CAS Registry Number 7439-49:
(6*7)+(5*4)+(4*3)+(3*9)+(2*4)+(1*9)=118
118 % 10 = 8
So 7439-49-8 is a valid CAS Registry Number.
