157153-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157153-38-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,5 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 157153-38:
(8*1)+(7*5)+(6*7)+(5*1)+(4*5)+(3*3)+(2*3)+(1*8)=133
133 % 10 = 3
So 157153-38-3 is a valid CAS Registry Number.

Enantioselective synthesis of all of the stereoisomers of (E)-13,14-dihydroxyretinol (DHR)
Alvarez, Susana,Alvarez, Rosana,De Lera, Angel R.
, p. 839 - 846 (2007/10/03)
The Stille cross-coupling of trienyliodide 4 and E-alkenylstannanes 5, derived from enantioenriched diols obtained by a Sharpless asymmetric dihydroxylation (SAD), provides a convergent route to all stereoisomers of 13,14-dihydroxyretinol (DHR), an immuno
