Check Digit Verification of cas no

The CAS Registry Mumber 19689-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,8 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 19689-20:
(7*1)+(6*9)+(5*6)+(4*8)+(3*9)+(2*2)+(1*0)=154
154 % 10 = 4
So 19689-20-4 is a valid CAS Registry Number.

Mild and efficient synthesis of propargylamines by copper-catalyzed Mannich reaction

Bieber, Lothar W.,Da Silva, Margarete F.

, p. 8281 - 8283 (2007/10/03)

Terminal alkynes can be condensed with aqueous formaldehyde and primary or secondary amines to give secondary and tertiary propargylamines. The reaction is best carried out in DMSO under CuI catalysis. Terminal alkynes undergo mild and efficient aminomethylation with aqueous formaldehyde and secondary amines under CuI catalysis. In most cases high to nearly quantitative yields of tertiary propargylamines are obtained in DMSO solution at room temperature. Aromatic, aliphatic and silylated acetylenes as well as alkynols can be used. Primary amines are less reactive and satisfactory yields of secondary propargylamines are obtained only with phenylacetylene.
