Check Digit Verification of cas no

The CAS Registry Mumber 100045-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,0,4 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 100045-90:
(8*1)+(7*0)+(6*0)+(5*0)+(4*4)+(3*5)+(2*9)+(1*0)=57
57 % 10 = 7
So 100045-90-7 is a valid CAS Registry Number.

SRN1 Reactions of Halocyclopropanes with Benzenethiolate Ion

Meijs, Gordon F.

, p. 606 - 611 (2007/10/02)

Ultraviolet irradiation of gem-dibromocyclopropanes 1 with benzenethiolate ion in liquid ammonia or in Me2SO solutions gave dithioacetals 2 and, in some cases, cyclopropyl phenyl sulfides 3.The reactions did not proceed in the dark and they were inhibited by m-dinitrobenzene, di-tert-butyl nitroxide, and oxygen.The bromocyclopropane 6a underwent a similar, but slower, reaction.Treatment of the bromochlorocyclopropane 7b led to replacement of only the bromine, while the dichlorocyclopropane 9b was inert under the reaction conditions.The results appear consistent with a radical chain mechanism.
