Check Digit Verification of cas no
The CAS Registry Mumber 503524-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,5,2 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 503524-25:
(8*5)+(7*0)+(6*3)+(5*5)+(4*2)+(3*4)+(2*2)+(1*5)=112
112 % 10 = 2
So 503524-25-2 is a valid CAS Registry Number.

A convenient synthesis of fourteen 4-methyl- and 4-phenylseleno-1,1,1-trihalo-3-alken-2-ones [CX3C(O)CH=CR1SeR, where X = F, Cl; R = Me, Ph; and R1 = H, alkyl, aryl] from the reaction of the corresponding 4-methoxy-1,1,1-trihalo-3-alken-2-ones with methyl- or phenylselenols in the presence of boron trifluoride etherate is reported. The reaction of 4-methylseleno-1,1,1-trihalo-3-alken-2-ones with bromine and ammonia lead to 3-trihalomethylisoselenazoles in good yields. The usefulness of the trichloromethyl group as a carboxyl group precursor was demonstrated by the conversion of 5-ethyl-3-trichloromethylisoselenazole to 5-ethyl-3-carboxyisoselenazole acid.
