15047-21-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 15047-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,0,4 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15047-21:
(7*1)+(6*5)+(5*0)+(4*4)+(3*7)+(2*2)+(1*1)=79
79 % 10 = 9
So 15047-21-9 is a valid CAS Registry Number.

A NEW SYNTHESIS OF 3H-PHENOXAZIN-3-ONES
Bird, C. W.,Latif, M.
, p. 529 - 534 (2007/10/02)
The reductive cyclisation of 3-hydroxy-2'-nitrodiphenyl ethers provides a new synthesis of 3H-phenoxazin-3-ones, which should be particularly suitable for the synthesis of actinomycins.
