Check Digit Verification of cas no

The CAS Registry Mumber 62155-38-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,1,5 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 62155-38:
(7*6)+(6*2)+(5*1)+(4*5)+(3*5)+(2*3)+(1*8)=108
108 % 10 = 8
So 62155-38-8 is a valid CAS Registry Number.

Coupling of Trifluoroacetaldehyde N-Triftosylhydrazone with Organoboronic Acids for the Synthesis of gem-Difluoroalkenes

Ma, Yu,Reddy, Bhoomireddy Rajendra Prasad,Bi, Xihe

, p. 9860 - 9863 (2019/12/24)

The synthesis of alkyl gem-difluoroalkenes remains a difficult task in organic synthesis. Here, we report a general and efficient approach for tackling this problem by gem-difluoroolefination of trifluoroacetaldehyde N-triftosylhydrazone with organoboronic acids. This protocol is operationally simple, free of transition metals, and suitable for a broad range of organoboronic acids. Moreover, the utility of the products was demonstrated by further conversion of the gem-difluorovinyl group.
