Check Digit Verification of cas no

The CAS Registry Mumber 31058-85-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,0,5 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 31058-85:
(7*3)+(6*1)+(5*0)+(4*5)+(3*8)+(2*8)+(1*5)=92
92 % 10 = 2
So 31058-85-2 is a valid CAS Registry Number.

Selective Methylation of Amides, N-Heterocycles, Thiols, and Alcohols with Tetramethylammonium Fluoride

Cheng, Hong-Gang,Pu, Maoping,Kundu, Gourab,Schoenebeck, Franziska

supporting information, p. 331 - 334 (2019/12/30)

We herein disclose the use of tetramethylammonium fluoride (TMAF) as a direct and selective methylating agent of a variety of amides, indoles, pyrroles, imidazoles, alcohols, and thiols. The method is characterized by operational simplicity, wide scope, and ease of purification. Our computational studies suggest a concerted methylation-deprotonation as the preferred reaction pathway.
