Check Digit Verification of cas no

The CAS Registry Mumber 71021-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,2 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 71021-25:
(7*7)+(6*1)+(5*0)+(4*2)+(3*1)+(2*2)+(1*5)=75
75 % 10 = 5
So 71021-25-5 is a valid CAS Registry Number.

Photolytische Decarbonylierung von Anhydrozucker-Ulosen zur Synthese von 1,5-Anhydro-β-D-lyxo- und -ribofuranosen sowie 2,6-Anhydro-β-D-psicofuranosen

Heyns, Kurt,Neste, Helmut-Rainer,Thiem, Joachim

, p. 891 - 908 (2007/10/02)

By photochemical decarbonylation of the 1,6-anhydro-2- (1) and -4-uloses (3) with D-lyxo configuration stereoselective ring contractions yield the 1,5-anhydro-β-D-lyxofuranose derivative 2.Via corresponding transformations the benzylidene derivative 9 is
