Check Digit Verification of cas no

The CAS Registry Mumber 91513-13-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,1 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91513-13:
(7*9)+(6*1)+(5*5)+(4*1)+(3*3)+(2*1)+(1*3)=112
112 % 10 = 2
So 91513-13-2 is a valid CAS Registry Number.

Efficient Synthesis of 4-Substituted 2,3-Anhydro Sugars from 2,4-Di-O-tosylates

Kowollik, Wolfgang,Voelter, Wolfgang

, p. 433 - 436 (2007/10/02)

Treatment of benzyl 2,4-di-O-p-tosyl-α-D-xylopyranoside (1) with sodium methoxide/methanol yields benzyl 3,4-anhydro-2-O-p-tosyl-β-L-arabinopyranoside (2) and benzyl 2,3-anhydro-4-O-p-tosyl-α-D-lyxopyranoside (3) in a ratio of 50 : 1.Reaction of 2 with sodium methoxide leads to benzyl 2,3-anhydro-4-O-methyl-α-D-lyxopyranoside (4) and with sodium azide to benzyl 2,3-anhydro-4-azido-4-deoxy-α-D-lyxopyranoside (5).In the latter synthesis small amounts of benzyl 3,4-diazido-3,4-dideoxy-α-D-arabinopyranoside (7) are formed as a side product.
