Check Digit Verification of cas no

The CAS Registry Mumber 103744-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,4 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 103744-87:
(8*1)+(7*0)+(6*3)+(5*7)+(4*4)+(3*4)+(2*8)+(1*7)=112
112 % 10 = 2
So 103744-87-2 is a valid CAS Registry Number.

Tannins and Related Compounds. LXXIX. Isolation and Characterization of Novel Dimeric and Trimeric Hydrolyzable Tannins, Nuphrins C, D, E and F, from Nuphar japonicum DC.

Ishimatsu, Makoto,Tanaka, Takashi,Nonaka, Gen-ichiro,Nishioka, Itsuo,Nishizawa, Makoto,Yamagishi, Takashi

, p. 1735 - 1743 (2007/10/02)

Four novel dimeric and trimeric hydrolyzable tannins, nupharins C (1), D, (13), E (15) and F (16), which possess a less favorable α-D-glucopyranose core with an atropisomeric (R)- or (S)-hexahydrodiphenoyl group at the 3,6-position, have been isolated from the rhizomes of Nuphar japonicum DC. (Nymphaeaceae).The structures of these compounds were established on the basis of spectroscopic and chemical evidence.Keywords - Nuphar japonicum; Nymphaeaceae; nupharin C-F; dimeric ellagitannin; trimeric ellagitannin; dehydrodigallic acid; α-D-glucose; R-, S-hexahydrodiphenoic acid; atropisomerism; diastereomer
