1334808-91-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1334808-91-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,8,0 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1334808-91:
(9*1)+(8*3)+(7*3)+(6*4)+(5*8)+(4*0)+(3*8)+(2*9)+(1*1)=161
161 % 10 = 1
So 1334808-91-1 is a valid CAS Registry Number.

Improved synthesis of cyclohexane-backbone iridium-complexes of quinoline-phosphine and their applications in asymmetric hydrogenation
Liu, Qibin
, (2020/09/15)
– The iridium-complexes 3 and 4 with cyclohexane-backbone derived from quinoline were easily synthesized. The key step is cis/trans stereoselective reduction of 2-(quinolin-2-yl)cyclohexanone 5 to trans-2-(quinolin-2-yl)cyclohexanol 6 using Al(Oi-Pr)3/i-P
