17791-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17791-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,7,9 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 17791-34:
(7*1)+(6*7)+(5*7)+(4*9)+(3*1)+(2*3)+(1*4)=133
133 % 10 = 3
So 17791-34-3 is a valid CAS Registry Number.

The First Efficient Asymmetric Synthesis of 7-Oxabicyclohept-5-ene-2-carboxylate Derivatives
Takayama, Hiromitsu,Iyobe, Akira,Koizumi, Toru
, p. 771 - 772 (2007/10/02)
The asymmetric synthesis of 7-oxabicyclohept-5-ene-2-carboxylate derivatives was accomplished by the highly diastereoselective Diels-Alder reaction of (S)S- and (R)S-3-(2-pyridylsulphinyl)acrylates with furan.
