1189119-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1189119-50-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,1,1 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1189119-50:
(9*1)+(8*1)+(7*8)+(6*9)+(5*1)+(4*1)+(3*9)+(2*5)+(1*0)=173
173 % 10 = 3
So 1189119-50-3 is a valid CAS Registry Number.
