Check Digit Verification of cas no

The CAS Registry Mumber 155872-02-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,8,7 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 155872-02:
(8*1)+(7*5)+(6*5)+(5*8)+(4*7)+(3*2)+(2*0)+(1*2)=149
149 % 10 = 9
So 155872-02-9 is a valid CAS Registry Number.

Total synthesis of macrosphelide M from diacetone glucose

Sharma, Gangavaram V. M.,Reddy, Post Sai

, p. 2414 - 2421 (2012)

The total synthesis of macrosphelide M is described. The key steps include the preparation of the acid and alcohol fragments from diacetone glucose and (S)-malic acid, respectively, followed by Yamaguchi esterification and macrocyclization of the tris-olefin by ring-closing metathesis. Finally, one-pot deprotection of the PMB and TBS groups with TiCl4 results in the target. The C-3/C-4 stereocenters of diacetone glucose are used for the introduction of four stereocenters, whereas the fifth stereocenter is realized from (S)-malic acid. The total synthesis of macrosphelide M was achieved from diacetone glucose and (S)-malic acid. The key steps include Yamaguchi esterification and macrocyclization of the tris-olefin by the second-generation Grubbs catalyst.
