Check Digit Verification of cas no

The CAS Registry Mumber 33542-30-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,5,4 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 33542-30:
(7*3)+(6*3)+(5*5)+(4*4)+(3*2)+(2*3)+(1*0)=92
92 % 10 = 2
So 33542-30-2 is a valid CAS Registry Number.

Production of N-(1-alkenyl)-carbamyl chlorides

-

, (2008/06/13)

The production of N-(1-alkenyl)-carbamyl chlorides by reaction of a Schiff base with phosgene, and the new N-(1-alkenyl)-carbamyl chlorides themselves. The new compounds which can be prepared by the process of the invention are valuable starting materials for the production of coating intermediates, plastics, paints and plant protection agents. One preferred group of compounds available from said process are the N-vinyl compounds of the formula STR1 in which R1 is cyclohexyl, cyclooctyl, norbornyl, tetrahydrodicyclopentadienyl, n-hexyl, n-octyl, 2-ethylhexyl or phenyl. Another preferred group of compounds are the N-vinyl-N-t-alkylcarbamyl chlorides of 4 to 6 carbon atoms in the tertiary alkyl group, especially N-vinyl-N-t-butylcarbamyl chloride.
