Check Digit Verification of cas no

The CAS Registry Mumber 150990-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,9,9 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 150990-68:
(8*1)+(7*5)+(6*0)+(5*9)+(4*9)+(3*0)+(2*6)+(1*8)=144
144 % 10 = 4
So 150990-68-4 is a valid CAS Registry Number.

Synthesis of (-)-muricatacin.

Makabe,Tanaka,Oritani

, p. 1028 - 1029 (1993)

The synthesis of (-)-muricatacin starting from 1-bromododecane and 2-pentyn-1-ol is described. 2-Pentadecyn-1-ol (4), which was prepared from 1-bromododecane (2) and 2-pentyn-1-ol (3), was converted to epoxy alcohol 6 through a two-step reaction sequence, 6 being successively submitted to tosylation, iodination, chain extension with tert-butyl lithioacetate, and acid-catalyzed cyclization to give (-)-muricatacin (1a). Recrystallization afforded optically pure 1a.
