Check Digit Verification of cas no

The CAS Registry Mumber 1018968-57-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,8,9,6 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1018968-57:
(9*1)+(8*0)+(7*1)+(6*8)+(5*9)+(4*6)+(3*8)+(2*5)+(1*7)=174
174 % 10 = 4
So 1018968-57-4 is a valid CAS Registry Number.

Synthesis of the sporolide ring framework through a cascade sequence involving an intramolecular [4+2] cycloaddition reaction of an o-quinone

Nicolaou,Wang, Jianhua,Tang, Yefeng

, p. 1432 - 1435 (2008)

(Chemical Equation Presented) Sea-ing is believing: The o-quinone indene intermediate 1 was generated from the corresponding catechol substrate and converted into macrocycle 2 by a cascade sequence involving a novel intramolecular [4+2] cycloaddition reaction. This sequence serves as the key process to form the core heptacyclic structure 3 of the marine-derived natural products sporolide A and B, which were isolated from the relevant actinomycete fermentation broths.
