Check Digit Verification of cas no

The CAS Registry Mumber 404936-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,4,9,3 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 404936-83:
(8*4)+(7*0)+(6*4)+(5*9)+(4*3)+(3*6)+(2*8)+(1*3)=150
150 % 10 = 0
So 404936-83-0 is a valid CAS Registry Number.

As part of the optimization process of the lead compound I a focussed library of diversely substituted pyridazin-3(2H)-ones containing a 3-oxo-3-phenylprop-1-en-1-yl or 3-phenylprop-2-enoyl fragment at position 5 has been obtained and evaluated as antipla

Pyridazines. Part 25: Efficient and selective deprotection of pharmacologically useful 2-MOM-pyridazinones using Lewis acids

Sotelo, Eddy,Coelho, Alberto,Ravi?a, Enrique

, p. 8633 - 8636 (2007/10/03)

An efficient and selective procedure for the cleavage of a methoxymethyl group at the 2-position in acid-sensitive pyridazinones is presented. Deprotection with Lewis acids (boron tribromide or aluminium chloride) affords 3(2H)-pyridazinones under mild co
