Check Digit Verification of cas no

The CAS Registry Mumber 1514894-42-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,1,4,8,9 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1514894-42:
(9*1)+(8*5)+(7*1)+(6*4)+(5*8)+(4*9)+(3*4)+(2*4)+(1*2)=178
178 % 10 = 8
So 1514894-42-8 is a valid CAS Registry Number.

Total synthesis of heronapyrrole C

Ding, Xiao-Bo,Furkert, Daniel P.,Capon, Robert J.,Brimble, Margaret A.

, p. 378 - 381 (2014/04/03)

A flexible total synthesis of the 2-nitropyrrole-derived marine natural product, (+)-heronapyrrole C, is reported. The approach is based on regioselective access to key building blocks containing the rare 4-substituted 2-nitropyrrole motif. Sharpless asymmetric epoxidation and dihydroxylation and a Shi epoxidation were used to introduce the five stereogenic centers of the bis-THF-diol side chain. The N-benzoyloxymethyl (Boz) protecting group was crucial for functionalization of the 2-nitropyrrole moiety and enabling final deprotection under mild conditions.
