144156-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144156-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,1,5 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 144156-68:
(8*1)+(7*4)+(6*4)+(5*1)+(4*5)+(3*6)+(2*6)+(1*8)=123
123 % 10 = 3
So 144156-68-3 is a valid CAS Registry Number.

Asymmetric synthesis of β,β-difluoroamino acids via cross-coupling and Strecker reactions
Wang, Xiao-Jin,Zhang, Fan,Liu, Jin-Tao
, p. 1731 - 1735 (2008/09/17)
β,β-Difluoroamino acids were synthesized from commercially available ethyl bromodifluoroacetate using cross-coupling and Strecker reactions as key steps. The coupling reaction of aryl iodides with ethyl bromodifluoroacetate gave the corresponding coupling
