Check Digit Verification of cas no

The CAS Registry Mumber 34003-77-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,0,0 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 34003-77:
(7*3)+(6*4)+(5*0)+(4*0)+(3*3)+(2*7)+(1*7)=75
75 % 10 = 5
So 34003-77-5 is a valid CAS Registry Number.

Aldol-cyclization reaction sequence for the synthesis of tetrahydrofurans

Calter, Michael A.,Sugathapala, Priyantha M.,Zhu, Cheng

, p. 3837 - 3840 (1997)

The aldol reactions of α-diazo-β-ketoesters with a variety of aldehydes produced adducts which underwent Rh(II)-catalyzed O-H insertion reaction to yield highly substituted tetrahydrofurans. Alkylation and decarboxylation of these tetrahydrofurans formed a wide variety of tetrahydrofuran structures.
