Check Digit Verification of cas no

The CAS Registry Mumber 944262-94-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,2,6 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 944262-94:
(8*9)+(7*4)+(6*4)+(5*2)+(4*6)+(3*2)+(2*9)+(1*4)=186
186 % 10 = 6
So 944262-94-6 is a valid CAS Registry Number.

Nodulisporic acid A synthetic studies. 1. Overall strategy and construction of a western hemisphere subtarget.

Smith 3rd.,Ishiyama,Cho,Ohmoto

, p. 3967 - 3970 (2001)

In this, the first of two Letters, we outline our overall strategy for the construction of (+)-nodulisporic acid A (1), a representative member of a new class of indole diterpenes. In addition, we describe the efficient assembly of (-)-6, an advanced western hemisphere subtarget, comprising the ABC rings of (+)-nodulisporic acid A (1). The synthesis proceeded in 9% overall yield (longest linear sequence, 11 steps), exploiting a Shibasaki-Mori tandem transmetalation-cyclization to construct ring B. [reaction: see text]
