477795-44-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 477795-44-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,7,9 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 477795-44:
(8*4)+(7*7)+(6*7)+(5*7)+(4*9)+(3*5)+(2*4)+(1*4)=221
221 % 10 = 1
So 477795-44-1 is a valid CAS Registry Number.
