Check Digit Verification of cas no

The CAS Registry Mumber 139005-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,0 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139005-44:
(8*1)+(7*3)+(6*9)+(5*0)+(4*0)+(3*5)+(2*4)+(1*4)=110
110 % 10 = 0
So 139005-44-0 is a valid CAS Registry Number.

CHEMISTRY OF α-NITROEPOXIDES: SYNTHESIS OF USEFUL INTERMEDIATES VIA NUCLEOPHILIC RING OPENING OF α-NITROEPOXIDES

Vankar, Yashwant D.,Shah, Kavita,Bawa, Anita,Singh, Surendra P.

, p. 8883 - 8906 (2007/10/02)

Various α-nitroepoxides are converted into corresponding 1,2-diketones via two different ways of ring opening viz. with Pd(O) and with DMSO/BF3*EtO2 (or ClSiMe3).In addition to this, a variety of nucleophiles are reacted with α-nitrocyclopentene oxide 6 and α-nitrocyclohexene oxide 7 to form the corresponding α-substituted ketones which are useful intermediates in organic synthesis.Two of the products so obtained viz. 32 and 33 are also transformed further into optically active thialactones 38 and 39 respectively via baker's yeast reduction followed by lactonisation.
