Check Digit Verification of cas no

The CAS Registry Mumber 41718-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,7,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 41718-40:
(7*4)+(6*1)+(5*7)+(4*1)+(3*8)+(2*4)+(1*0)=105
105 % 10 = 5
So 41718-40-5 is a valid CAS Registry Number.

Sulfonium ion-promoted traceless Schmidt reaction of alkyl azides

Ardiansah, Bayu,Kakiuchi, Kiyomi,Morimoto, Tsumoru,Tanimoto, Hiroki,Tomohiro, Takenori

, p. 8738 - 8741 (2021/09/08)

Schmidt reaction by sulfonium ions is described. General primary, secondary, and tertiary alkyl azides were converted to the corresponding carbonyl or imine compounds without any trace of the activators. This bond scission reaction through 1,2-migration of C-H and C-C bonds was accessible to the one-pot substitution reaction.
