Check Digit Verification of cas no

The CAS Registry Mumber 182967-16-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,9,6 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 182967-16:
(8*1)+(7*8)+(6*2)+(5*9)+(4*6)+(3*7)+(2*1)+(1*6)=174
174 % 10 = 4
So 182967-16-4 is a valid CAS Registry Number.

Structure and synthesis of phlobatannins related to the (4β,6:4α,8)- bis-fisetinidol-catechin profisetinidin triflavanoid

Bonnet, Susan L.,Steynberg, Jan P.,Bezuidenhoudt, Barend C. B.,Saunders, Catharina M.,Ferreiradagger, Daneel

, p. 215 - 228 (2007/10/03)

Several members of the class of natural phlobatannins, representing the products of stereoselective pyran rearrangement of the 2,3-trans-3,4-trans- and 3,4-cis-flavan-3-ol units in the (4β,6:4α,8)-bis-fisetinidol-catechin triflavanoid have been characterized. These comprise a functionalized hexahydro-dipyrano-[2,3-f:2',3'h]-chromene, two fisetinidol-(4α, 10)- tetrahydropyrano[2,3-f]chromenes and a pair of fisetinidol-(4α,10)- tetrahydropyrano[3,2-g]chromenes. The proposed structures of these novel compounds were confirmed by synthesis via base-catalysed conversion of the 4- O(E)-methyl ether of their presumed triflavanoid biogenetic precursor.
