Check Digit Verification of cas no

The CAS Registry Mumber 290834-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,8,3 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 290834-74:
(8*2)+(7*9)+(6*0)+(5*8)+(4*3)+(3*4)+(2*7)+(1*4)=161
161 % 10 = 1
So 290834-74-1 is a valid CAS Registry Number.

Diastereoselective synthesis of bis(3,5)pyrazolophanes by sequential inter- and intramolecular cycloadditions of homochiral nitrilimines

Broggini, Gianluigi,Molteni, Giorgio,Pilati, Tullio

, p. 1975 - 1983 (2007/10/03)

Starting from ethyl (S)-lactate as the chiral unit, we have developed the synthesis of the enantiopure bis(3,5)pyrazolophanes 9 and 19 by means of sequential inter- and intramolecular cycloadditions of nitrilimine intermediates. Copyright (C) 2000 Elsevie
