6139-73-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6139-73-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,3 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6139-73:
(6*6)+(5*1)+(4*3)+(3*9)+(2*7)+(1*3)=97
97 % 10 = 7
So 6139-73-7 is a valid CAS Registry Number.
