1431291-10-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1431291-10-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,2,9 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1431291-10:
(9*1)+(8*4)+(7*3)+(6*1)+(5*2)+(4*9)+(3*1)+(2*1)+(1*0)=119
119 % 10 = 9
So 1431291-10-9 is a valid CAS Registry Number.

Synthesis of atorvastatin lactone linker constructs for target fishing
Sawant, Pramod,Maier, Martin E.
, p. 6576 - 6585 (2013/01/15)
With the aim of connecting atorvastatin lactone 9 to a linker for affinity-based target fishing, a concise route to the pyrrolecarboxylic acid 8 was developed. Key features of the synthesis of the diol-containing side-chain were a catalytic enantioselecti
