Check Digit Verification of cas no
The CAS Registry Mumber 5026-12-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,2 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5026-12:
(6*5)+(5*0)+(4*2)+(3*6)+(2*1)+(1*2)=60
60 % 10 = 0
So 5026-12-0 is a valid CAS Registry Number.

Thermal decomposition of 4-(4-hydroxyphenyl)-2,2,4-trimethylchromane (1) gives 2,2,4-trimelhyl-2H-chromen (2) and 2,2-dimethyl-4-methylenechroman (3). Under influence of hydrochloric acid, 3 isomerizes smoothly to 2. Under similar reaction conditions 2′-hydroxy-2,4,4-trimethylflavan (4) is transformed into 2 and 2,4,4-trimethyl-4H-chromen (5); elimination of the phenol moiety is accompanied with a rearrangement. Opening of the pyran ring with subsequent re-cyclization seems to be more reliable expia nation of this transformation than simple 1-3 migration of the methyl group.
