Check Digit Verification of cas no

The CAS Registry Mumber 960119-51-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,6,0,1,1 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 960119-51:
(8*9)+(7*6)+(6*0)+(5*1)+(4*1)+(3*9)+(2*5)+(1*1)=161
161 % 10 = 1
So 960119-51-1 is a valid CAS Registry Number.

Cycloisomerization of Carbamoyl Chlorides in Hexafluoroisopropanol: Stereoselective Synthesis of Chlorinated Methylene Oxindoles and Quinolinones

Bajohr, Jonathan,Lautens, Mark,Mirabi, Bijan,Rodríguez, José F.,Whyte, Andrew,Zhang, Anji

, p. 18478 - 18483 (2021)

Hexafluoroisopropanol (HFIP) was employed as an additive for the generation of 3-(chloromethylene)oxindoles via the chloroacylation of alkyne-tethered carbamoyl chlorides. This reaction avoids the use of a metal catalyst and accesses products in high yields and stereoselectivities. Additionally, this reaction is scalable and proved amenable to a series of product derivatizations, including the synthesis of nintedanib. The reactivity of alkene-tethered carbamoyl chlorides with hexafluoroisopropanol (HFIP) was harnessed towards the synthesis of 2-quinolinones.
