Check Digit Verification of cas no

The CAS Registry Mumber 1439298-21-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,9,2,9 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1439298-21:
(9*1)+(8*4)+(7*3)+(6*9)+(5*2)+(4*9)+(3*8)+(2*2)+(1*1)=191
191 % 10 = 1
So 1439298-21-1 is a valid CAS Registry Number.

Synthesis and characterization of pyrrole-containing microporous polymeric networks

Yang, Yanqin,Zhang, Qiang,Zheng, Jifu,Zhang, Suobo

, p. 3254 - 3260 (2013)

Two types of microporous polymeric networks have been prepared from monomers containing N-tert-butoxycarbonyl-protected pyrrole by FeCl 3-mediated oxidative coupling polymerization. These materials were predominantly microporous (with BET surface areas of 828 m2 g -1 and 1408 m2 g-1), exhibiting high CO 2 uptake capacities (1.96 mmol g-1 and 2.69 mmol g -1 at 273 K, 1 bar). Novel microporous polymeric films (with BET surface areas of 570 m2 g-1 and 593 m2 g -1) were fabricated through in situ polymerization of monomers on a flat glass dish using a sol-gel process catalyzed by trifluoroacetic acid.
