945859-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 945859-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,5,8,5 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 945859-57:
(8*9)+(7*4)+(6*5)+(5*8)+(4*5)+(3*9)+(2*5)+(1*7)=234
234 % 10 = 4
So 945859-57-4 is a valid CAS Registry Number.
