467-57-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 467-57-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 467-57:
(5*4)+(4*6)+(3*7)+(2*5)+(1*7)=82
82 % 10 = 2
So 467-57-2 is a valid CAS Registry Number.

Zou, Peng,Fu, Jing,Yu, He-Shui,Zhang, Jie,Kang, Li-Ping,Ma, Bai-Ping,Yan, Xian-Zhong

, p. 1090 - 1095 (2008/02/04)

The detailed NMR studies and full assignments of the 1H and 13C spectral data for two new furostanol saponins isolated from Agave sisalana leaves are described. Their structures were established using a combination of 1D and 2D NMR techniques including 1H, 13C, 1H-1H COSY, TOCSY, HSQC, HMBC and HSQC-TOCSY, and also FAB-MS spectrometry and chemical methods. The structures were established as (25S)-26-(β-D-glucopyranosyl)-22ξ-hydroxyfurost-12-one-3β-yl-O- α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→3) -O-[O-β-D-glucopyranosyl-(1→2)]-O-β-D-glucopyranosyl-(1→4) -β-D-galactopyranoside (1) and (25S)-26-(β-D-glucopyranosyl)-22ξ- hydroxyfurost-5-en-12-one-3ξ-yl-O-α-L-rhamnopyranosyl-(1→4) -β-D-glucopyranosyl-(1→3)-O-[O-β-D-glucopyranosyl-(1→2)] -O-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside (2).
