Check Digit Verification of cas no

The CAS Registry Mumber 856377-28-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,3,7 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 856377-28:
(8*8)+(7*5)+(6*6)+(5*3)+(4*7)+(3*7)+(2*2)+(1*8)=211
211 % 10 = 1

MONOMERIC AND OLIGOMERIC UNSATURATED VICINAL DITHIOETHERS AND THEIR USE FOR SELECTIVE PALLADIUM (II) SEPARATION FROM SECONDARY RAW MATERIALS

-

Page/Page column 24, (2013/03/26)

The present invention relates to unsaturated vicinal dithioethers of general formula (I) wherein n is an integer from 1 to 12, wherein m is 0 or 1, wherein X is selected from formules wherein Y is selected from the group consisting of -CH2,-[-CH2,-O-CH2]3, -CH2- CH2-CH2-, -CH2- CH2-O-, -O-CH2-CH2-, -CH2-CH2-O-CH2-, and -CH2-O-CH2-CH2-; wherein, under the proviso that n is 1, m is 1 and R1 and R2 each are H; wherein, under the proviso that n > 1, R1 and R2 are selected from the group consisting of H, Na, CI, and Br, or R1 and R2 together form a bond making up a cycle. Furthermore the invention relates to mixtures of oligomeric unsaturated dithioethers according to the invention, to the use of the compounds and mixtures according to the invention in the separation of Pd (II) and to supports comprising the dithioethers according to the invention.
