1347628-00-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1347628-00-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,7,6,2 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1347628-00:
(9*1)+(8*3)+(7*4)+(6*7)+(5*6)+(4*2)+(3*8)+(2*0)+(1*0)=165
165 % 10 = 5
So 1347628-00-5 is a valid CAS Registry Number.

Synthesis of naphtho[1,2-e]-pyrazolo[5,1-b][1,3]oxazines
Osyanin,Nakushnov,Klimochkin
experimental part, p. 755 - 757 (2012/01/30)
The previously unknown heterocyclic system naphtho[1,2-e]pyrazolo[5,1-b][1, 3]oxazine was synthesized by the condensation of 1-dimethylaminomethyl-2- naphthols with bromopyrazoles. It is proposed that the highly reactive o-methylenequinone of the naphthal
