Check Digit Verification of cas no

The CAS Registry Mumber 69905-88-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,0 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 69905-88:
(7*6)+(6*9)+(5*9)+(4*0)+(3*5)+(2*8)+(1*8)=180
180 % 10 = 0
So 69905-88-0 is a valid CAS Registry Number.

Effect of pressure on the Strecker synthesis of hindered α-aminonitriles from ketones and aromatic amines

Jenner, Gérard,Salem, Ridha Ben,Kim, Jong Chul,Matsumoto, Kiyoshi

, p. 447 - 449 (2007/10/03)

The effect of high pressure is examined in Strecker reactions involving ketones, amines and trimethylsilyl cyanide. This effect is small when moderately hindered reactants are involved. However, in the case of aniline and N-methylaniline, the sensitivity of the reaction to pressure increases with increasing steric bulk of the alkyl groups of the ketone. The results confirm the merit of pressure activation as sterically demanding reactions are subject to higher pressure acceleration than their unhindered analogs.
