Check Digit Verification of cas no

The CAS Registry Mumber 642409-45-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,4,0 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 642409-45:
(8*6)+(7*4)+(6*2)+(5*4)+(4*0)+(3*9)+(2*4)+(1*5)=148
148 % 10 = 8
So 642409-45-8 is a valid CAS Registry Number.

Improved synthesis of 1,4-dideoxy-1,4-imino-D-galactitol, an inhibitor of E. coli K12 UDP-Gal mutase and mycobacterial galactan biosynthesis

Pham-Huu, Duy-Phong,Gizaw, Yonas,BeMiller, James N.,Petru?, Ladislav

, p. 9413 - 9417 (2003)

The E. Coli K12 UDP-Gal mutase inhibitor 1 was prepared from D-glucose in 5 steps (42% overall yield). The 4-azido galactose derivative 11, leading to 1, was formed by treatment of galactose dithioacetal 7 with mercuric oxide and mercuric chloride in acet

New synthesis of 1,4-dideoxy-1,4-imino-D-galactitol from D-glucose propane-1,3-diyl dithioacetal

Pham-Huu, Duy-Phong,Gizaw, Yonas,BeMiller, James N,Petru?, Ladislav

, p. 383 - 385 (2002)

The treatment of 4-azido-4-deoxy-2,3:5,6-di-O-isopropylidene-D-galactose propane-1,3-diyl dithioacetal (derived from D-glucose) with mercuric chloride and mercuric oxide in aqueous acetone afforded 4-azido-4-deoxy-2,3:5,6-di-O-isopropylidene-D-galactose.
