Check Digit Verification of cas no

The CAS Registry Mumber 87057-27-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,5 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87057-27:
(7*8)+(6*7)+(5*0)+(4*5)+(3*7)+(2*2)+(1*7)=150
150 % 10 = 0
So 87057-27-0 is a valid CAS Registry Number.

The reaction of 1,6,6aλ4-trithiapentalenes with carbene and nitrene reagents

McKinnon, David M.

, p. 1161 - 1165 (2007/10/02)

The reaction of some 1,6,6aλ4-trithiapentalenes with ethyl azidoformate provides 1:1 adducts, formulated as 4-thioacyl-methylene-1,3,2-dithiazine-2-carboxylic esters; and with diphenyldiazomethane, 1:2 adducts, formulated as 4-(3-propenylidene)-1,3-dithiins.In some cases 4-diphenylmethylenethiopyrans are isolated.The products arise by insertion at a disulfide type bond, or on a thione function of an initial reaction product.
