144674-69-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144674-69-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,7 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144674-69:
(8*1)+(7*4)+(6*4)+(5*6)+(4*7)+(3*4)+(2*6)+(1*9)=151
151 % 10 = 1
So 144674-69-1 is a valid CAS Registry Number.

Enantioselective synthesis of carbocyclic showdomycin derivative via asymmetric Diels-Alder reaction of (S(S))-3-(2-pyridylsulphinyl)acrylate
Takahashi,Kotsubo,Koizumi
, p. 1035 - 1040 (2007/10/02)
The first enantioselective synthesis of a carbocyclic analogue of showdomycin, 3-[(1S,2S,3R,4R)-2,3-(isopropylidenedioxy)-4-(pivaloxymethyl)cyclopent yl]maleimide 1, has been accomplished using the asymmetric Diels-Alder reaction of the (S(S))-3-(2-pyridy
