Check Digit Verification of cas no

The CAS Registry Mumber 110637-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,6,3 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 110637-98:
(8*1)+(7*1)+(6*0)+(5*6)+(4*3)+(3*7)+(2*9)+(1*8)=104
104 % 10 = 4
So 110637-98-4 is a valid CAS Registry Number.

Electron-Transfer Substitution Reactions: Stereochemistry

Kornblum, Nathan,Wade, Peter A.

, p. 5301 - 5305 (2007/10/02)

Substitution of the aliphatic nitro group of optically active 2-(p-nitrophenyl)-2-nitrobutane (II) by sodium azide, sodium thiophenoxide, sodium benzenesulfinate, and the lithium salt of 2-nitropropane invariably occurs with complete loss of optical activity.Furthermore, levorotatory II is racemized by sodium nitrite.These facts support the view that substitution reactions in p-nitrocumyl systems proceed via the electron-transfer chain mechanism of eq 2-5.
