Check Digit Verification of cas no

The CAS Registry Mumber 117707-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,7,0 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 117707-20:
(8*1)+(7*1)+(6*7)+(5*7)+(4*0)+(3*7)+(2*2)+(1*0)=117
117 % 10 = 7
So 117707-20-7 is a valid CAS Registry Number.

STEREOSELECTIVE SYNTHESES OF 2-SUBSTITUTED PERHYDROFUROFURANS

Vader, Jan,Koopmans, Rimco,Groot, Aede De,Veldhuizen, Albertus van,Kerk, Sies van der

, p. 2663 - 2674 (2007/10/02)

New reagents for the stereoselective synthesis of 2-substituted perhydrofurofurans are described.In the successful approach towards the latter compounds, the key steps were the addition of a monolithio-2α-methoxy-3β-perhydrofuran to an aldehyde and a dilithio-2α-methoxy-3β-perhydrofuran to a carboxyl derivative, respectively.The structures and conformations of the 2-tert-butyl- and 2-isopropylperhydrofurofurans were examined by means of (1)H-NMR double resonance and the 2D-NOE spectroscopy.
