160911-78-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 160911-78-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,9,1 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 160911-78:
(8*1)+(7*6)+(6*0)+(5*9)+(4*1)+(3*1)+(2*7)+(1*8)=124
124 % 10 = 4
So 160911-78-4 is a valid CAS Registry Number.

Cohen, Or,Mishani, Eyal,Rozen, Shlomo
experimental part, p. 3579 - 3582 (2010/07/04)
Organic trifluoromethyl derivatives were made from aromatic and aliphatic carboxylic acids by transforming them first into the corresponding dithioesters followed by reaction with bromine trifluoride under mild conditions (0 °C, 2 min).
