Check Digit Verification of cas no
The CAS Registry Mumber 5253-46-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,5 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5253-46:
(6*5)+(5*2)+(4*5)+(3*3)+(2*4)+(1*6)=83
83 % 10 = 3
So 5253-46-3 is a valid CAS Registry Number.

A useful sequence of reactions for the syntheses of a variety of heterocyclic systems including an oxadiazepine ring is described. The key step involves the condensation of substituted 2,2′-(1,2-ethanediyldiimino)bisphenols with ethanedial to provide stereoselectively the 6a,7a-trans-6,6a,7a,8,15,16-hexahydro[1,4]benzoxazine[4′,3′:6,7] [1,3,6]oxadiazepino[2,3-c][1,4]-benzoxazine-6,8-diol framework, as established by X-ray diffraction analyses.
