Check Digit Verification of cas no

The CAS Registry Mumber 1226922-68-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,6,9,2 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1226922-68:
(9*1)+(8*2)+(7*2)+(6*6)+(5*9)+(4*2)+(3*2)+(2*6)+(1*8)=154
154 % 10 = 4
So 1226922-68-4 is a valid CAS Registry Number.

The thiocarbonyl 'S' is softer than thiolate 'S': A catalyst-free one-pot synthesis of isothiocyanates in water

Jamir, Latonglila,Ali, Abdur Rezzak,Ghosh, Harisadhan,Chipem, Francis A. S.,Patel, Bhisma K.

, p. 1674 - 1678 (2010)

Treatment of the preformed or the in situ generated aryl/alkyl dithiocarbamates triethylammonium salt (ArNHCSS-.Et 3NH+) with methyl acrylate in an aqueous medium gave solely arylisothiocyanate (ArNCS), whereas the in situ generated aryl dithiocarbamic acid (ArNHCSS-.H+) yielded exclusively the thia-Michael adduct (ArNHCSSCH2CH2COOMe). This differential reactivity can be explained by two alternative mechanisms which is dependent both on the nature of the counter cation and on the pH of the reaction medium. Irrespective of the counter cations, the thiocarbonyl sulfur (=S) atom, having large orbital-coefficient, is softer compared to the thiol/thiolate sulfur (-SH/S-) in a dithiocarbamate salt and the former adds to the Michael acceptor by a 1,4-addition.
