Check Digit Verification of cas no

The CAS Registry Mumber 437757-80-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,7,7,5 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 437757-80:
(8*4)+(7*3)+(6*7)+(5*7)+(4*5)+(3*7)+(2*8)+(1*0)=187
187 % 10 = 7
So 437757-80-7 is a valid CAS Registry Number.

A new route to exo-glycals using the Ramberg-Baecklund rearrangement

Griffin, Frank K.,Paterson, Duncan E.,Murphy, Paul V.,Taylor, Richard J. K.

, p. 1305 - 1322 (2002)

A new route to exo-glycals 4 is described in which glycosyl sulfones 3 are subjected to the Meyers variant of the Ramberg-Baecklund rearrangement. The conversion of sulfones derived from glucose, galactose, mannose, cellobiose, and ribose into di-, tri-, and tetra-substituted alkenes is reported. Preliminary mechanistic studies of this process are also described. Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002.
