1189349-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1189349-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,3,4 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1189349-40:
(9*1)+(8*1)+(7*8)+(6*9)+(5*3)+(4*4)+(3*9)+(2*4)+(1*0)=193
193 % 10 = 3
So 1189349-40-3 is a valid CAS Registry Number.
