1190933-75-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1190933-75-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,9,3 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1190933-75:
(9*1)+(8*1)+(7*9)+(6*0)+(5*9)+(4*3)+(3*3)+(2*7)+(1*5)=165
165 % 10 = 5
So 1190933-75-5 is a valid CAS Registry Number.
