Check Digit Verification of cas no

The CAS Registry Mumber 88793-67-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,7,9 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 88793-67:
(7*8)+(6*8)+(5*7)+(4*9)+(3*3)+(2*6)+(1*7)=203
203 % 10 = 3
So 88793-67-3 is a valid CAS Registry Number.

THIONES AS SUPERDIPOLAROPHILES

Huisgen, Rolf,Langhals, Elke

, p. 5369 - 5372 (2007/10/02)

According to kinetic measurements,the 1,3-cycloadditions of diphenyl-diazomethane to thioketones are much faster than those to α,β-unsaturated carbonyl compounds and nitriles previously regarded as record dipolarophiles.The primary cycloadducts are tetrasubstituted 1,3,4-thiadiazolines which extrude N2 and furnish thiiranes via thiocarbonyl ylides.

NEW THIOCARBONYL YLIDES FROM THIOBENZOPHENONE

Huisgen, Rolf,Xingya, Li

, p. 2363 - 2368 (2007/10/02)

Thiobenzophenone is converted to 1,3,4-thiadiazolines by reaction with diazoethane, phenyldiazomethane or diphenyldiazomethane at -78 deg C.Extrusion of nitrogen from the thiadiazolines furnishes thiocarbonyl ylides which, in turn, undergo electrocyclic r
