Check Digit Verification of cas no

The CAS Registry Mumber 155197-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,1,9 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 155197-91:
(8*1)+(7*5)+(6*5)+(5*1)+(4*9)+(3*7)+(2*9)+(1*1)=154
154 % 10 = 4
So 155197-91-4 is a valid CAS Registry Number.

D-Glucosamine propanedithioacetal, an efficient chiral auxiliary in β-lactam chemistry

Anaya, Josefa,Gero, Stephane D.,Grande, Manuel,Hernando, Jose Ignacio M.,Laso, Nieves M.

, p. 837 - 850 (2007/10/03)

The synthesis of some monocyclic β-lactams (monobactams) by the Staudinger reaction using d-glucosamine propanedithioacetal as chiral auxiliary is reported. The influence of several radicals at C3, C4, and C(1') (sugar moiety) as well as other structural aspects are considered in relation to the antielastase activity.
