1353641-73-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1353641-73-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,6,4 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1353641-73:
(9*1)+(8*3)+(7*5)+(6*3)+(5*6)+(4*4)+(3*1)+(2*7)+(1*3)=152
152 % 10 = 2
So 1353641-73-2 is a valid CAS Registry Number.

Synthesis and spectral properties of 3,3′-bis(dipyrrolylmethene)
Dudina,Berezin,Guseva,Semeikin
experimental part, p. 2352 - 2354 (2012/03/12)
Bis(2,4,7,8,9-pentamethyldipyrrolylmethene-3-yl)(4′-methoxyphenyl) methane dihydrobromide was synthesized and its spectral properties were studied. It was found that the basicity of the ligand 3,3′-bis-(dipyrrolylmethene) decreases upon insertion of the m
