Check Digit Verification of cas no
The CAS Registry Mumber 29397-21-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,3,9 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 29397-21:
(7*2)+(6*9)+(5*3)+(4*9)+(3*7)+(2*2)+(1*1)=145
145 % 10 = 5
So 29397-21-5 is a valid CAS Registry Number.

β-(Cycloalkylamino)ethanesulfonyl azides as novel water-soluble reagents for the synthesis of diazo compounds and heterocycles

[Figure not available: see fulltext.] Novel water-soluble sulfonyl azides were synthesized, which are basic by nature. The obtained compounds were used as donors of the diazo group in the diazo transfer reaction. Due to their good solubility in water and high polarity, the byproducts formed in this case were easily separated from the desired products by washing with water or column chromatography. It was also shown that new sulfonyl azides as a result of reactions can be incorporated in heterocyclic products, imparting them water solubility.
