Check Digit Verification of cas no

The CAS Registry Mumber 1286209-74-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,2,0 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1286209-74:
(9*1)+(8*2)+(7*8)+(6*6)+(5*2)+(4*0)+(3*9)+(2*7)+(1*4)=172
172 % 10 = 2
So 1286209-74-2 is a valid CAS Registry Number.

Synthetic route discovery and introductory optimization of a novel process to idebenone

Tsoukala, Anna,Bjorsvik, Hans-Rene

, p. 673 - 680 (2011/12/01)

An environmentally benign, convenient, high yielding, and cost-effective synthesis leading to idebenone is disclosed. The synthesis includes a bromination process for the preparation of 2-bromo-3,4,5-trimethoxy-1- methylbenzene, a protocol for the Heck cross-coupling reaction using either thermal or microwave heating, olefin reduction by palladium catalyzed hydrogenation, and a green oxidation protocol with hydrogen peroxide as oxidant to achieve the benzoquinone framework. The total synthesis is composed of six steps that provide an overall yield of 20% that corresponds to a step yield of 76%.
