Check Digit Verification of cas no
The CAS Registry Mumber 3834-42-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,3 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3834-42:
(6*3)+(5*8)+(4*3)+(3*4)+(2*4)+(1*2)=92
92 % 10 = 2
So 3834-42-2 is a valid CAS Registry Number.

The preparation of a variety of novel perfluoroalkyl-substituted compounds in high yields using easily prepared (perfluoroalkyl)trimethylsilanes (1a - c) is described. (Trifluoromethyl)-, (pentafluoroethyl)-, and (heptafluoropropyl)trimethylsilane, 1a - c, respectively, react readily with carbonyl compounds, such as aldehydes and ketones, by a fluoride-initiated catalytic process.Fluoride-initiated addition of 1 to a carbonyl group generates an oxyanionic species which then further catalyzes the reaction.Even enolizable carbonyl compounds react cleanly under the reaction conditions.A study of the scope of the reactivity of 1a toward other carbonyl groups in esters, lactones and an acid chloride was also carried out.Thus 1a reacts cleanly with five- and six-membered ring lactones.However, unactivated esters do not react under the reaction conditions.The acid chloride reacts with 1a to give a mixture of products.
