55439-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55439-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,4,3 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 55439-47:
(7*5)+(6*5)+(5*4)+(4*3)+(3*9)+(2*4)+(1*7)=139
139 % 10 = 9
So 55439-47-9 is a valid CAS Registry Number.
