85329-43-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85329-43-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,3,2 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85329-43:
(7*8)+(6*5)+(5*3)+(4*2)+(3*9)+(2*4)+(1*3)=147
147 % 10 = 7
So 85329-43-7 is a valid CAS Registry Number.

NEW MASKED BUILDING BLOCK FOR ISOPRENOID POLYENE CHAIN SYNTHESIS
Mandai, T.,Iuchi, Y.,Suzuki, K.,Kawada, M.,Otera, J.
, p. 4721 - 4724 (2007/10/02)
The new building blocks 2, 3, and 4 have been effectively synthesized starting from 2-hydroxymethyl-4-phenylthio-1-butene (1a).A convenient synthesis of retinoic acid methyl ester (9) using 2 is also described.
