Check Digit Verification of cas no

The CAS Registry Mumber 25109-26-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,0 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 25109-26:
(7*2)+(6*5)+(5*1)+(4*0)+(3*9)+(2*2)+(1*6)=86
86 % 10 = 6
So 25109-26-6 is a valid CAS Registry Number.

THE ACTION OF THIOLS ON DERIVATIVES OF D-XYLOSE

Blumberg, Karl,Es, Theodorus van

, p. 253 - 266 (2007/10/02)

The action of thiols on 1,2,3,4-tetra-O-acetyl β-D-xylopyranose gave 2- and 5-alkylthiopentose dithioacetals and alkyl 1-thio-D-xylopyranosides.On treatment with thiols and trifluoroacetic acid, 3-O-acetyl-1,2-O-isopropylidene-α-D-xylofuranose derivatives rapidly formed 4-O-acetyl-2,3-dialkylthio-D-ribose dithioacetal derivatives, which were in turn converted into 4-O-acetyl-3-S-benzyl-2,5-epithio-3-thio-D-ribose (or D-arabinose) dithioacetal.
