Check Digit Verification of cas no

The CAS Registry Mumber 918544-05-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,5,4 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 918544-05:
(8*9)+(7*1)+(6*8)+(5*5)+(4*4)+(3*4)+(2*0)+(1*5)=185
185 % 10 = 5
So 918544-05-5 is a valid CAS Registry Number.

Construction of the key amino alcohol moiety of the cinchona alkaloids

Kobayashi, Yuichi,Motoyama, Yuuya

, p. 2670 - 2672 (2008/09/16)

An N-Teoc [CO2(CH2)2TMS] protected form of the amino alcohol moiety found in the cinchona alkaloids was constructed by Curtius rearrangement followed by reaction of the isocyanate intermediate with TMS(CH2)2OH in one pot. Deprotection of the TV-Teoc protective group and subsequent piperidine ring formation were easily accomplished with CsF in DMF at 110 °C in one pot to afford model compounds of the alkaloids.
