Check Digit Verification of cas no

The CAS Registry Mumber 845777-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,5,7,7 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 845777-72:
(8*8)+(7*4)+(6*5)+(5*7)+(4*7)+(3*7)+(2*7)+(1*2)=222
222 % 10 = 2
So 845777-72-2 is a valid CAS Registry Number.

Mild, Efficient, One-Pot Synthesis of Imidazolones Promoted by N,O-Bistrimethylsilylacetamide (BSA)

Muselli, Micka?l,Colombeau, Ludovic,Hédouin, Jonathan,Hoarau, Christophe,Bischoff, Laurent

, p. 2819 - 2825 (2016/12/14)

The formation of imidazolones by means of dehydrative cyclization was developed, using bistrimethylsilylacetamide. This highly versatile, friendly, safe, and cost-effective reagent exhibited a very large scope of starting materials, since it can promote the formation of 4-benzylidene imidazolones, 4,4-dialkyl-imidazolones, bearing alkyl, aryl, or even no substituent at C2, the latter being unavailable by classical methods. This reagent also afforded clean and high-yielding one-pot reactions in the presence of amine or imine reagents.
