1169840-89-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1169840-89-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,9,8,4 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1169840-89:
(9*1)+(8*1)+(7*6)+(6*9)+(5*8)+(4*4)+(3*0)+(2*8)+(1*9)=194
194 % 10 = 4
So 1169840-89-4 is a valid CAS Registry Number.
