Check Digit Verification of cas no

The CAS Registry Mumber 1292299-76-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,2,2,9 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1292299-76:
(9*1)+(8*2)+(7*9)+(6*2)+(5*2)+(4*9)+(3*9)+(2*7)+(1*6)=193
193 % 10 = 3
So 1292299-76-3 is a valid CAS Registry Number.

New Vilsmeier reaction for facile synthesis of 4-phenyl-2,4- dihydrochromeno[4,3-c]pyrazoles with Bis(trichloromethyl) carbonate/DMF

Chen, Zhiwei,Yang, Yanyan,Su, Weike

, p. 661 - 664 (2011/03/18)

An efficient method for the synthesis of 4-phenyl-2,4-dihydrochromeno[4,3- c]pyrazoles via the cyclisation reaction of the easily available flavanone-4-arylhydrazones with Vilsmeier reagent (Bis(trichloromethyl) carbonate/DMF) has been developed.
