1303613-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1303613-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,3,6,1 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1303613-40:
(9*1)+(8*3)+(7*0)+(6*3)+(5*6)+(4*1)+(3*3)+(2*4)+(1*0)=102
102 % 10 = 2
So 1303613-40-2 is a valid CAS Registry Number.

, p. 396 - 398 (2011/04/22)
Tetramethylcyclobutadiene-AlClcomplex reacted with bisalkynes possessing phenylene and biphenylene spacer giving rise to mono- and bis-Dewar benzenes. The rearrangement of the bis-Dewar benzene derivatives under thermal conditions (150 C) yielded the corr
