1421-85-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1421-85-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,2 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1421-85:
(6*1)+(5*4)+(4*2)+(3*1)+(2*8)+(1*5)=58
58 % 10 = 8
So 1421-85-8 is a valid CAS Registry Number.

GENERAL SYNTHETIC ROUTES TO DIARENE OXIDES OF POLYCYCLIC AROMATIC HYDROCARBONS
Agarwal, Shiv K.,Boyd, Derek R.,Jennings, W. Brian,McGuckin, Rosaleen M.,O'Kane, Gerard A.
, p. 123 - 126 (2007/10/02)
Diarene oxides have been synthetized by a single step oxidation of monoarene oxides using dimethyldioxirane, and by a three step cyclization sequence from the appropriate trans-tetrahydrobromoacetate precursors.
