1143523-52-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1143523-52-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,3,5,2 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1143523-52:
(9*1)+(8*1)+(7*4)+(6*3)+(5*5)+(4*2)+(3*3)+(2*5)+(1*2)=117
117 % 10 = 7
So 1143523-52-7 is a valid CAS Registry Number.
