Check Digit Verification of cas no

The CAS Registry Mumber 85428-54-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,4,2 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 85428-54:
(7*8)+(6*5)+(5*4)+(4*2)+(3*8)+(2*5)+(1*4)=152
152 % 10 = 2
So 85428-54-2 is a valid CAS Registry Number.

SELECTIVE CLEAVAGE OF THE CARBON-SULPHUR AND CARBON-OXYGEN BONDS IN METHOXYTHIOANISOLES

Testaferri, L.,Tiecco, M.,Tingoli, M.,Chianelli, D.,Maiolo, F.

, p. 2721 - 2724 (2007/10/02)

Selective cleavage of thioether or ether functions in methoxythioanisoles in hexamehtylphosphoramide (HMPA) with sodium gives methoxythiophenols by cleavage of the carbon-sulphur bond.Reactions with sodium isopropanethiolate give instead the thiomethoxyphenols by dealkylation of the methoxy function.When the methoxythioanisoles were treated first with sodium isopropanethiolate and then with sodium complete dealkylation was achieved with formation of mercaptophenols.The present methods have considerable advantages over existing procedures for the synthesis of methoxythiophenols, thiomethoxyphenols and mercaptophenols.The mechanistic implications of the reactions investigated are also discussed.
