Check Digit Verification of cas no

The CAS Registry Mumber 13035-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,3 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13035-49:
(7*1)+(6*3)+(5*0)+(4*3)+(3*5)+(2*4)+(1*9)=69
69 % 10 = 9
So 13035-49-9 is a valid CAS Registry Number.

Reaction of organocuprate reagents with protected 1,2-anhydro sugars. Stereocontrolled synthesis of 2-deoxy-C-glycosyl compounds

Bellosta,Czernecki

, p. 275 - 284 (2007/10/02)

The reaction of protected 1,2-anhydro-α-D-gluco- and β-D-manno-pyranoses with alkyl and phenyl organocuprates afforded the corresponding C-glycosyl compounds in acceptable to high yield. Complete stereocontrol was obtained, leading respectively to the β-D or the α-D anomer. With the perbenzylated manno derivative, deoxygenation at C-2 was achieved in high yield, affording 2-deoxy-α-D-C-glycosyl compounds.
