1169837-25-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1169837-25-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,9,8,3 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1169837-25:
(9*1)+(8*1)+(7*6)+(6*9)+(5*8)+(4*3)+(3*7)+(2*2)+(1*5)=195
195 % 10 = 5
So 1169837-25-5 is a valid CAS Registry Number.
