292858-20-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 292858-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,2,8,5 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 292858-20:
(8*2)+(7*9)+(6*2)+(5*8)+(4*5)+(3*8)+(2*2)+(1*0)=179
179 % 10 = 9
So 292858-20-9 is a valid CAS Registry Number.

Copper-catalysed rearrangement of 4-substituted-2,3-1H-benzoxazine-1-thiones
Agirbas, Hikmet,Guener, Selahattin
, p. 257 - 263 (2007/10/03)
4-Substituted-2,3-1H-benzoxazine-1-thiones were prepared by the treatment of the corresponding benzoxazine-1-ones with P2S5. The thermal rearrangement of 4-substituted-2,3-1H-benzoxazine-1-thiones, catalysed by metallic copper, yield
