Check Digit Verification of cas no

The CAS Registry Mumber 113686-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,6,8 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 113686-43:
(8*1)+(7*1)+(6*3)+(5*6)+(4*8)+(3*6)+(2*4)+(1*3)=124
124 % 10 = 4
So 113686-43-4 is a valid CAS Registry Number.

Preparation of N-alkyl 2-pyridones via a lithium iodide promoted oto N-alkyl migration: Scope and mechanism

Tasker, Sarah Z.,Bosscher, Michael A.,Shandro, Christina A.,Ryu, Keun Ah,Snapper, Gregory S.,Utter, Jarrad M.,Anderson, Carolyn E.,Lanni, Erica L.,Ellsworth, Bruce A.

, p. 8220 - 8230,11 (2020/10/15)

An efficient and inexpensive LiI-promoted O- to N-alkyl migration of 2-benzyloxy-, 2-allyloxy-, and 2-propargyloxypyridines and heterocycles is reported. The reaction produces the corresponding N-alkyl 2-pyridones and analogues under green, solvent-free conditions in good to excellent yields (30 examples, 20-97% yield). This method has been shown to be intermolecular and requires heat and lithium cation to occur.
