Check Digit Verification of cas no

The CAS Registry Mumber 92039-31-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,0,3 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 92039-31:
(7*9)+(6*2)+(5*0)+(4*3)+(3*9)+(2*3)+(1*1)=121
121 % 10 = 1
So 92039-31-1 is a valid CAS Registry Number.

Cu-Catalyzed alkylation-cyanation type difunctionalization of styrenes with aliphatic aldehydes and TMSCN via decarbonylation

Zhou, Yu-Ling,Chen, Jun-Jia,Cheng, Jing,Yang, Luo

supporting information, p. 1231 - 1235 (2022/02/19)

A copper-catalyzed decarbonylative alkylation-cyanation of styrene derivatives with aliphatic aldehydes and trimethylsilyl cyanide to provide chain elongated nitriles is reported. Using TBHP as an oxidant and free radical initiator, the reaction can smoothly convert abundant α-di-substituted, α-mono-substituted and linear aliphatic aldehydes into the corresponding 3°, 2° and 1° alkyl radicals to initiate the subsequent radical-type difunctionalization of various styrenes.
