118157-85-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118157-85-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,1,5 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 118157-85:
(8*1)+(7*1)+(6*8)+(5*1)+(4*5)+(3*7)+(2*8)+(1*5)=130
130 % 10 = 0
So 118157-85-0 is a valid CAS Registry Number.

SYNTHESIS OF 2,3-DIHYDRO-1H-PHENALENE DERIVATIVE BY THE INTRAMOLECULAR DIELS-ALDER REACTION OF BENZYNE WITH FURAN
Darlington, W. H.,Szmuszkovicz, J.
, p. 1883 - 1886 (2007/10/02)
2,3-Dihydro-1H-phenalene derivative 1 was synthesized by the intramolecular Diels-Alder reaction (21->22). 2,5-Dimethylpyrrole was used as a protecting group for the primary amine.
