944539-57-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 944539-57-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,5,3 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 944539-57:
(8*9)+(7*4)+(6*4)+(5*5)+(4*3)+(3*9)+(2*5)+(1*7)=205
205 % 10 = 5
So 944539-57-5 is a valid CAS Registry Number.
