1171119-05-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1171119-05-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,1,1,1 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1171119-05:
(9*1)+(8*1)+(7*7)+(6*1)+(5*1)+(4*1)+(3*9)+(2*0)+(1*5)=113
113 % 10 = 3
So 1171119-05-3 is a valid CAS Registry Number.
