Check Digit Verification of cas no

The CAS Registry Mumber 1352034-36-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,0,3 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1352034-36:
(9*1)+(8*3)+(7*5)+(6*2)+(5*0)+(4*3)+(3*4)+(2*3)+(1*6)=116
116 % 10 = 6
So 1352034-36-6 is a valid CAS Registry Number.

Synthesis of (±)- and (+)-perovskone

Majetich, George,Zhang, Yong,Tian, Xinrong,Britton, Jonathan E.,Li, Yang,Phillips, Ryan

, p. 10129 - 10146 (2012/02/03)

A biomimetic synthesis of the triterpene (±)-perovskone was achieved featuring a remarkable polycyclization process in which three rings, four bonds, and five stereocenters were created in a single operation in 82% yield. This convergent synthesis required 16 steps, starting from vanillin, and proceeded in 9% overall yield. A second route to prepare optically active quinone 2 took 15 steps in 36% overall yield and featured a palladium-catalyzed reductive allylic transposition to establish the C-5 chirality stereospecifically. Quinone (-)-2 was converted to (+)-perovskone (1) via a polycyclization cascade, which created four rings, five bonds, and six stereocenters in a single operation in 50% yield.
