Check Digit Verification of cas no

The CAS Registry Mumber 54844-25-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,8,4 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 54844-25:
(7*5)+(6*4)+(5*8)+(4*4)+(3*4)+(2*2)+(1*5)=136
136 % 10 = 6
So 54844-25-6 is a valid CAS Registry Number.

Base-catalyzed selective esterification of alcohols with unactivated esters

Zhang, Chunyan,Zhang, Guoying,Luo, Shizhong,Wang, Chunfu,Li, Huiping

supporting information, p. 8467 - 8471 (2018/12/01)

A practical and efficient base-catalyzed esterification has been developed for the facile synthesis of a broad range of esters from simple alcohols with unactivated tert-butyl esters. This protocol could be conducted at mild conditions, providing esters in high to excellent yields with good functional tolerance. Mechanistic studies provided evidence of an exchange of the tert-butyl alkoxide metal with the alcohol, producing a new alkoxide to participate in the transesterification reaction.
