1168157-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1168157-68-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,8,1,5 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1168157-68:
(9*1)+(8*1)+(7*6)+(6*8)+(5*1)+(4*5)+(3*7)+(2*6)+(1*8)=173
173 % 10 = 3
So 1168157-68-3 is a valid CAS Registry Number.
