Check Digit Verification of cas no

The CAS Registry Mumber 99254-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,5 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99254-50:
(7*9)+(6*9)+(5*2)+(4*5)+(3*4)+(2*5)+(1*0)=169
169 % 10 = 9
So 99254-50-9 is a valid CAS Registry Number.

supporting information, p. 4201 - 4206 (2020/06/04)

An efficient intramolecular Pd-catalyzed N-arylation of o-iodo-amidosugars for the synthesis of N-glycosylated oxindoles has been reported. The coupling reaction takes place in toluene and involves Pd(OAc)2/RuPhos catalytic systems in the presence of K2CO3. This versatile approach was extended successfully to the synthesis of other N-glycosylated heterocycles.
