254430-68-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 254430-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,4,4,3 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 254430-68:
(8*2)+(7*5)+(6*4)+(5*4)+(4*3)+(3*0)+(2*6)+(1*8)=127
127 % 10 = 7
So 254430-68-7 is a valid CAS Registry Number.

Catalytic Enantioselective Aza-Benzoin Reactions of Aldehydes with 2H-Azirines
Peng, Qiupeng,Guo, Donghui,Bie, Jianbo,Wang, Jian
, (2018)
The unprecedented enantioselective aza-benzoin reaction of aldehydes with 2H-azirines was developed by utilizing a chiral N-heterocyclic carbene as the catalyst. A wide range of corresponding aziridines can be obtained in good yields with high enantiosele
