Check Digit Verification of cas no

The CAS Registry Mumber 42940-75-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,9,4 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42940-75:
(7*4)+(6*2)+(5*9)+(4*4)+(3*0)+(2*7)+(1*5)=120
120 % 10 = 0
So 42940-75-0 is a valid CAS Registry Number.

Organotin-catalyzed synthesis of hydroxyalkylamides from lactones via a ring-opening process

Liang, Xiayu,Yu, Peng,Fu, Chen,Shen, Yongcun

, (2021)

A new strategy for the facile synthesis of hydroxyalkylamides through the ring-opening reaction of lactone with amine promoted by dibutyltin acetate was developed. A series of hydroxyalkylamide compounds were obtained and the method was successfully applied to the synthesis of pharmaceutically active molecules tyrosinase inhibitor V and HDAC inhibitor VI via a three-step synthetic pathway. The broad substrate scope, mild reaction conditions and practical application proved the effectiveness, compatibility and practicality of this method.
