Check Digit Verification of cas no

The CAS Registry Mumber 263406-16-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,4,0 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 263406-16:
(8*2)+(7*6)+(6*3)+(5*4)+(4*0)+(3*6)+(2*1)+(1*6)=122
122 % 10 = 2
So 263406-16-2 is a valid CAS Registry Number.

Total synthesis of (±)-desoxycodeine-D: A novel route to the morphine skeleton

Liou, Jing-Ping,Cheng, Chen-Yu

, p. 915 - 918 (2000)

A novel approach towards the construction of the morphine skeleton was demonstrated by a total synthesis of (±)-desoxycodeine-D (11) from 5,6,7,8- tetrahydroisoquinoline and isovanillin. The key steps are two consecutive Pd- catalyzed cyclizations and a Stevens rearrangement for the formation of ring B. (C) 2000 Elsevier Science Ltd.
