Check Digit Verification of cas no

The CAS Registry Mumber 33856-05-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,8,5 and 6 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 33856-05:
(7*3)+(6*3)+(5*8)+(4*5)+(3*6)+(2*0)+(1*5)=122
122 % 10 = 2
So 33856-05-2 is a valid CAS Registry Number.

An expedient one-pot tandem method for the synthesis of 3-(2-(phenylamino)thiazol-4-yl)-2H-chromen-2-ones under green conditions

Kavitha,Srikrishna,Dubey, Pramod Kumar,Aparna

, p. 1913 - 1921 (2019/04/30)

This paper describes a facile pathway for the one-pot three-component synthesis of 3-(2-(phenylamino)thiazol-4-yl)-2H-chromen-2-ones starting from ethyl-4-chloroacetoacetate by treating it with equimolar amounts of various phenylthioureas independently re

PEG-600 mediated one-pot reaction of 3-acetyl-2: H -chromen-2-one with heterylthiols and phenylthioureas using tetrabutylammonium tribromide as an efficient green reagent
