Check Digit Verification of cas no
The CAS Registry Mumber 672309-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,2,3,0 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 672309-94:
(8*6)+(7*7)+(6*2)+(5*3)+(4*0)+(3*9)+(2*9)+(1*4)=173
173 % 10 = 3
So 672309-94-3 is a valid CAS Registry Number.

, (2020/09/16)
The invention discloses a preparation method of a ceftobiprole intermediate, namely (R)-1-benzyl-3-aminopyrrolidine. The preparation method specifically comprises the following steps: with D-asparticacid as an initial raw material, carrying out amino protection, esterification, reduction, bromination cyclization and 3-amino protection removal successively to obtain (R)-1-benzyl-3-aminopyrrolidine. According to the method, the defects that raw materials for preparing (R)-1-benzyl-3-aminopyrrolidine are expensive, high temperature and high pressure are needed, precious metal is used for catalysis and the like in the prior art are overcome. All the materials used in the invention are cheap and easily available, so cost is low; and reactions can be carried out at normal temperature, so energyconsumption is low, industrial production is facilitated, and pollution is small.
