898751-99-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 898751-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,8,7,5 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 898751-99:
(8*8)+(7*9)+(6*8)+(5*7)+(4*5)+(3*1)+(2*9)+(1*9)=260
260 % 10 = 0
So 898751-99-0 is a valid CAS Registry Number.

Catalytic asymmetric hydrogenation of δ-ketoesters: Highly efficient approach to chiral 1,5-diols
Yang, Xiao-Hui,Xie, Jian-Hua,Liu, Wei-Peng,Zhou, Qi-Lin
, p. 7833 - 7836 (2013)
High turnover: An highly efficient catalytic asymmetric hydrogenation of δ-aryl-δ-ketoesters has been realized by using the chiral spiroiridium catalyst (R)-1. Chiral 1,5-diol products are obtained with excellent enantioselectivity and turnover numbers (TONs) as high as 100 000. TOF=turnover frequency. Copyright
