1426847-87-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1426847-87-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,8,4 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1426847-87:
(9*1)+(8*4)+(7*2)+(6*6)+(5*8)+(4*4)+(3*7)+(2*8)+(1*7)=191
191 % 10 = 1
So 1426847-87-1 is a valid CAS Registry Number.

Asymmetric Synthesis of L-carbidopa based on a highly enantioselective α-amination
Pericas, Lex,Shafir, Alexandr,Vallribera, Adelina
, p. 1448 - 1451 (2013)
A stereoselective synthesis of l-carbidopa in seven steps and 50% overall yield from commercial compounds is described. The key step involves a highly enantioselective α-amination reaction of an acyclic β-ketoester with di-tert-butyl azodicarboxylate indu
