Check Digit Verification of cas no

The CAS Registry Mumber 178406-02-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,4,0 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 178406-02:
(8*1)+(7*7)+(6*8)+(5*4)+(4*0)+(3*6)+(2*0)+(1*2)=145
145 % 10 = 5
So 178406-02-5 is a valid CAS Registry Number.

Synthesis and reactivity of aldehydes of the adamantane series

Voloboev,Butenko,Novakov

, p. 1121 - 1125 (2007/10/03)

1-Adamantanecarbonitriles are very active in the Stephen reaction, which allows synthesis of the corresponding aldehydes in high yields. Electron-acceptor substituents in the 3 position of the adamantine nucleus exert almost no effect on the yield of aldehydes. Separation of the nitrile group and the adamantane nucleus by one methylene group results in a complete loss of reactivity. A quantitative study of the reactivity of the synthesized aldehydes in the oximation reaction was performed.
