439277-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 439277-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,2,7 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 439277-57:
(8*4)+(7*3)+(6*9)+(5*2)+(4*7)+(3*7)+(2*5)+(1*7)=183
183 % 10 = 3
So 439277-57-3 is a valid CAS Registry Number.
