Check Digit Verification of cas no

The CAS Registry Mumber 160238-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,2,3 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 160238-48:
(8*1)+(7*6)+(6*0)+(5*2)+(4*3)+(3*8)+(2*4)+(1*8)=112
112 % 10 = 2
So 160238-48-2 is a valid CAS Registry Number.

Total synthesis of (+)-tautomycin

Shimizu, Satoshi,Nakamura, Sei-Ichi,Nakada, Masahisa,Shibasaki, Masakatsu

, p. 13363 - 13408 (2007/10/03)

A convergent stereocontrolled total synthesis of (+)-tautomycin (1), a specific inhibitor of protein serine/threonine phosphatases, has been achieved through an esterification of the C1.-C7. fragment A'74 with the C1-C26 fragment B'76 by a modified Yamaguchi method and an aldol reaction of the C17-C26 fragment C 5 with the C1-C16 fragment D 6 using LDA as key steps. The fragments 5 and 6 have been constructed in a stereocontrolled manner, respectively.
