Check Digit Verification of cas no

The CAS Registry Mumber 203052-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,0,5 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 203052-59:
(8*2)+(7*0)+(6*3)+(5*0)+(4*5)+(3*2)+(2*5)+(1*9)=79
79 % 10 = 9
So 203052-59-9 is a valid CAS Registry Number.

Total synthesis of methyl 14-hydroxy-(all-cis)-5,8,11-tetradecatrienoate: A useful intermediate for the synthesis of arachidonic acid analogues

Han, Luning,Razdan, Raj K.

, p. 771 - 774 (2007/10/03)

The first total synthesis of methyl 14-hydroxy-(all-cis)-5,8,11-tetradecatrienoate (1a) was accomplished in 11 steps with an overall yield of 14%. Major sequences involve Cu(I) catalyzed propargylic substitution of propargyl bromide 5 by 3-butyn-1-ol, followed by partial reduction of the diyne 6 to the cis,cis-diene 7, and Wittig reaction of the phosphonium iodide 9 with aldehyde 11 to the all-cis skipped triene 10.
