945774-45-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 945774-45-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,5,7,7 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 945774-45:
(8*9)+(7*4)+(6*5)+(5*7)+(4*7)+(3*4)+(2*4)+(1*5)=218
218 % 10 = 8
So 945774-45-8 is a valid CAS Registry Number.
