110523-57-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 110523-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,5,2 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 110523-57:
(8*1)+(7*1)+(6*0)+(5*5)+(4*2)+(3*3)+(2*5)+(1*7)=74
74 % 10 = 4
So 110523-57-4 is a valid CAS Registry Number.
