Check Digit Verification of cas no

The CAS Registry Mumber 139259-68-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,5 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139259-68:
(8*1)+(7*3)+(6*9)+(5*2)+(4*5)+(3*9)+(2*6)+(1*8)=160
160 % 10 = 0
So 139259-68-0 is a valid CAS Registry Number.

Electrodimerization ofN-Alkoxyamides for the Synthesis of Hydrazines

Nasier, Abudulajiang,Chang, Xihao,Guo, Chang

, p. 16068 - 16076 (2021/09/18)

An efficient and valuable N-N dimerization reaction ofN-alkoxyamides is reported under undivided electrolytic conditions. This electrochemical strategy provides a powerful way to access a wide range of advanced, highly functionalized hydrazines. Remarkably, anN-centered radical generated from the cleavage of the N-H bond under electrolytic conditions plays a crucial role in this transformation. Furthermore, variousN-alkoxyamides bearing different substituents are suitable in this transformation, furnishing the corresponding hydrazines in up to 92% yield.
