1145788-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1145788-23-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,5,7,8 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1145788-23:
(9*1)+(8*1)+(7*4)+(6*5)+(5*7)+(4*8)+(3*8)+(2*2)+(1*3)=173
173 % 10 = 3
So 1145788-23-3 is a valid CAS Registry Number.
