145450-70-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145450-70-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,4,5 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 145450-70:
(8*1)+(7*4)+(6*5)+(5*4)+(4*5)+(3*0)+(2*7)+(1*0)=120
120 % 10 = 0
So 145450-70-0 is a valid CAS Registry Number.

Diastereofacial selectivity in Diels-Alder reactions of chiral 2-substituted-1,3-dienes
Bloch,Chaptal-Gradoz
, p. 6147 - 6150 (2007/10/02)
Starting from chloroprene, an improved synthesis of alkyl and aryl (1,3-butadien-2-yl) methanols 1 is described. Thermal Diels-Alder reactions between these dienols or their ethers 3 and various dienophiles give rise with fair to good regio- and diastereo
