Check Digit Verification of cas no

The CAS Registry Mumber 1242319-66-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,3,1 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1242319-66:
(9*1)+(8*2)+(7*4)+(6*2)+(5*3)+(4*1)+(3*9)+(2*6)+(1*6)=129
129 % 10 = 9
So 1242319-66-9 is a valid CAS Registry Number.

Total syntheses of dalesconol A and B

Snyder, Scott A.,Sherwood, Trevor C.,Ross, Audrey G.

supporting information; experimental part, p. 5146 - 5150 (2010/11/04)

(Chemical equation Presented) (Chemical equation Presented) A polycyclic collapse: Use of a carefully designed acyclic intermediate participated in a cascade reaction that formed the entire core of the polyketide-derived dalesconols in a single flask (see scheme). A number of additional and carefully controlled synthetic operations completed an expeditious synthesis of both of these highly bioactive natural products as well as structural congenors.
