Check Digit Verification of cas no

The CAS Registry Mumber 1010729-21-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,0,7,2 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1010729-21:
(9*1)+(8*0)+(7*1)+(6*0)+(5*7)+(4*2)+(3*9)+(2*2)+(1*1)=91
91 % 10 = 1
So 1010729-21-1 is a valid CAS Registry Number.

Formate ester synthesis via reaction of 2-bromoethylamines with dimethylformamide

Dakanali, Marianna,Tsikalas, George K.,Krautscheid, Harald,Katerinopoulos, Haralambos E.

, p. 1648 - 1651 (2008/09/19)

2-Bromoethylamines are converted to the corresponding formate esters in the presence of DMF. Both primary and secondary bromides are smoothly transformed to the esters in satisfactory yields. The reaction mechanism involves the formation of an aziridinium ion, which upon reaction with DMF forms a Vilsmeier-type intermediate that is further hydrolyzed to the corresponding formates. Participation of the β-amino group appears to control not only the regioselectivity but also the stereoselectivity of the reaction. Application of the reaction conditions to chiral substrates indicated that non-rearranged products are formed with retention of configuration at the reacting center.
