Check Digit Verification of cas no

The CAS Registry Mumber 1268670-52-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,6,7 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1268670-52:
(9*1)+(8*2)+(7*6)+(6*8)+(5*6)+(4*7)+(3*0)+(2*5)+(1*2)=185
185 % 10 = 5
So 1268670-52-5 is a valid CAS Registry Number.

Synthesis of C-glycosylated amino acids by hetero-Diels-Alder addition of ethyl 2-nitrosoacrylate to exo-glycals

Massen, Zoe S.,Sarli, Vassiliki C.,Coutouli-Argyropoulou, Evdoxia,Gallos, John K.

, p. 230 - 237 (2011)

C-Glycoamino acids bearing a variety of sugar moieties were prepared by the hetero-Diels-Alder addition of ethyl 2-nitrosoacrylate to exo-glycals. The reaction proceeds smoothly to yield spirocyclic oxazines that can be converted into useful products by several hydrogenolytic techniques.
