156774-71-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 156774-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,7,7 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 156774-71:
(8*1)+(7*5)+(6*6)+(5*7)+(4*7)+(3*4)+(2*7)+(1*1)=169
169 % 10 = 9
So 156774-71-9 is a valid CAS Registry Number.

Rhodium-catalyzed and zinc(II)-triflate-promoted asymmetric hydrogenation of tetrasubstituted α,β-unsaturated ketones

Calvin, Joel R.,Frederick, Michael O.,Laird, Dana L. T.,Remacle, Jacob R.,May, Scott A.

, p. 1038 - 1041 (2012/04/10)

The asymmetric hydrogenation of tetrasubstituted α,β-unsaturated ketones has been accomplished using an in situ formed rhodium-Josiphos catalyst. The reaction is enhanced by addition of catalytic zinc(II) triflate, which significantly improves turnover fr
