Check Digit Verification of cas no

The CAS Registry Mumber 202145-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,1,4 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 202145-92:
(8*2)+(7*0)+(6*2)+(5*1)+(4*4)+(3*5)+(2*9)+(1*2)=84
84 % 10 = 4
So 202145-92-4 is a valid CAS Registry Number.

Practical synthesis of unsymmetrical polyamine amides

Blagbrough, Ian S.,Geall, Andrew J.

, p. 439 - 442 (2007/10/03)

Desymmetrisation of readily available symmetrical polyamines is an important first step in the synthesis of many polyamine containing natural products. Likewise in the synthesis of polyamine amides which are potentially useful for gene delivery and as neuroprotectants, based upon channel blocking toxins found in certain wasp and spider venoms. The application of trifluoroacetyl as a protecting group allows unsymmetrical polyamine amides to be easily prepared on a gram scale.
