Check Digit Verification of cas no
The CAS Registry Mumber 167073-08-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,0,7 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 167073-08:
(8*1)+(7*6)+(6*7)+(5*0)+(4*7)+(3*3)+(2*0)+(1*8)=137
137 % 10 = 7
So 167073-08-7 is a valid CAS Registry Number.

Novel process for synthesizing 2 -fluorocyclopropylamine with high selectivity and asymmetric synthesis
-
Paragraph 0070-0072, (2021/10/13)
A novel highly selective asymmetric synthesis process of 2 -fluorocyclopropylamine (Structural I). The method provided by the invention uses 1 - fluorine -1 - benzene (propylene) sulfonyl methane and chiral epichlorohydrin to construct chiral cyclopropane under basic conditions, and a new synthetic route not only achieves a special cis-trans selectivity, but also has a highly specific stereoselectivity. The synthesis route is efficient, the reaction condition is mild, the method is suitable for large industrial production in a green environment, 2 -fluorocyclopropylamine production cost is greatly reduced.
