Check Digit Verification of cas no

The CAS Registry Mumber 442901-00-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,2,9,0 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 442901-00:
(8*4)+(7*4)+(6*2)+(5*9)+(4*0)+(3*1)+(2*0)+(1*0)=120
120 % 10 = 0
So 442901-00-0 is a valid CAS Registry Number.

Amidination of amines under microwave conditions using recyclable polymer-bound 1H-pyrazole-1-carboxamidine

Solodenko, Wladimir,Broeker, Patrick,Messinger, Josef,Schoen, Uwe,Kirschning, Andreas

, p. 461 - 466 (2007/10/03)

A convenient one-step transformation of primary and secondary amines into the corresponding unprotected guanidines using 4-benzyl-3,5-dimethyl-1H- pyrazole-1-carboxamidine and its polymer-bound variant is described. The scopes and limitations of the method, the microwave-assistance of amidination as well as a recycling protocol are examined. Georg Thieme Verlag Stuttgart.

A new reagent and its polymer-supported variant for the amidination of amines

Dr?ger, Gerald,Solodenko, Wladimir,Messinger, Josef,Sch?n, Uwe,Kirschning, Andreas

, p. 1401 - 1403 (2007/10/03)

New reagents for the high yielding amidination of primary and secondary amines are described. By attaching a benzyl substituent to the 3,5-dimethyl-1H-pyrazole-1-carboxamidine ring, a reagent 1 is obtained which allows easy work-up after amidination because of solubility of byproducts in organic solvents. In addition, the polystyrene-bound analogue 2 was prepared which allows amidination of various amines with high purity.
