443646-85-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 443646-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,3,6,4 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 443646-85:
(8*4)+(7*4)+(6*3)+(5*6)+(4*4)+(3*6)+(2*8)+(1*5)=163
163 % 10 = 3
So 443646-85-3 is a valid CAS Registry Number.

Asymmetric synthesis of a structurally simplified analogue of the antibiotic heptelidic acid
Krenn, Maria,Urban, Ernst
, p. 127 - 137 (2007/10/03)
A structurally simplified analogue of the antibiotic (+)-heptelidic acid was synthesized in ten steps with an overall yield of 9%. Key step was a conjugate addition of a silyl protected vinylcuprate to an asymmetrically shielded enoate, which gave an addu
