Check Digit Verification of cas no

The CAS Registry Mumber 400051-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,0,0,5 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 400051-58:
(8*4)+(7*0)+(6*0)+(5*0)+(4*5)+(3*1)+(2*5)+(1*8)=73
73 % 10 = 3
So 400051-58-3 is a valid CAS Registry Number.

Synthesis of a prenylated and immunosuppressive marine galactosphingolipid with cyclopropane-containing alkyl chains: (2S,3R,11S,12R,2?R,5?Z,11?S,12?R)-Plakoside A and its (2S,3R,11R,12S,2?R,5?Z,11?R,12?)Isomer

, p. 3797 - 3809 (2001)

Plakoside A (1) {(2S,3R,11R*,12S*)-2-[(2? R,5? Z,11? R*, 12? S*)-2?-hydroxy-11?, 12?-methylene-5?-docosen-amido]-1-O-[2′-O- (3″-methyl-2″-butenyl)-β-D-galactopyranosyl]-11,12- methylene-1,3-docosanediol} is a prenylated galactosphingolipid isolated as an immunosuppressant from the marine sponge Plakortis simplex. (2S,3R,11S,12R,2? R,5? Z,11? S,12? R)-Plakoside A (1) has been synthesized by combining the sphingosine part 16, the α-hydroxy acid part 28, and the prenylated sugar part 33. (2S,3R,11R,12S,2? R,5? Z,11? R,12? S)-Plakoside A (1′) has also been synthesized.
