862539-91-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 862539-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,2,5,3 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 862539-91:
(8*8)+(7*6)+(6*2)+(5*5)+(4*3)+(3*9)+(2*9)+(1*1)=201
201 % 10 = 1
So 862539-91-1 is a valid CAS Registry Number.

Catalytic Asymmetric (3 + 3) Cycloaddition of Oxyallyl Zwitterions with α-Diazomethylphosphonates
Liu, Yan,Peng, Xian,Peng, Yungui,She, Rui,Zhou, Xin
, p. 7295 - 7300 (2021/10/01)
The unique structure of oxyallyls represents a significant challenge for their catalytic asymmetric applications. Herein, an unprecedented chiral imidodiphosphoric acid-catalytic enantioselective (3 + 3) cycloaddition between oxyallyl zwitterions generate
