1569309-79-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1569309-79-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,3,0 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1569309-79:
(9*1)+(8*5)+(7*6)+(6*9)+(5*3)+(4*0)+(3*9)+(2*7)+(1*9)=210
210 % 10 = 0
So 1569309-79-0 is a valid CAS Registry Number.

Practical asymmetric catalytic synthesis of spiroketals and chiral diphosphine ligands
Wang, Xiaoming,Wang, Xubin,Guo, Peihua,Wang, Zheng,Ding, Kuiling
, p. 2900 - 2907 (2013)
A practical procedure has been developed for efficient synthesis of chiral aromatic spiroketals and the relevant diphosphine ligands. The procedure includes first asymmetric hydrogenation of readily available α, α'-bis(2-benzyloxyarylidene) ketones cat-al
