441332-02-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 441332-02-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,1,3,3 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 441332-02:
(8*4)+(7*4)+(6*1)+(5*3)+(4*3)+(3*2)+(2*0)+(1*2)=101
101 % 10 = 1
So 441332-02-1 is a valid CAS Registry Number.

Site selectivity in [2 + 2] photocycloadditions of tricyclic 'diethenylbenzenes' to 2,3-dilnethylbut-2-ene
Bethke, John,Margaretha, Paul
, p. 544 - 551 (2007/10/03)
Upon irradiation at wavelengths above 390 nm in the presence of 2,3-dimethylbut-2-ene, both the newly synthesized pyranoquinolinedione 8 and thiinobenzopyrandione 9 selectively afford one of two possible photocycloadducts, 23 and 24, respectively.
