Check Digit Verification of cas no

The CAS Registry Mumber 1086572-34-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,8,6,5,7 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1086572-34:
(9*1)+(8*0)+(7*8)+(6*6)+(5*5)+(4*7)+(3*2)+(2*3)+(1*4)=170
170 % 10 = 0
So 1086572-34-0 is a valid CAS Registry Number.

Intramolecularly two-centered cooperation catalysis for the synthesis of cyclic carbonates from CO2 and epoxides

Zhang, Xiang,Jia, Yin-Bao,Lu, Xiao-Bing,Li, Bo,Wang, Hui,Sun, Li-Cheng

supporting information; experimental part, p. 6589 - 6592 (2009/04/06)

A catalyst system containing an electrophilic center and a sterically hindered nucleophilic center in one molecule was applied to the cycloaddition reaction of CO2 and epoxides. This intramolecularly two-centered cooperation catalyst showed activity even at a high [epoxide]/[catalyst] ratio up to 50 000 under mild conditions such as solvent-free, ambient temperature, and low CO2 pressure. The reaction of CO2 with (S)-propylene oxide at 80 °C in the presence of the bifunctional catalyst gives (S)-propylene carbonate in 96% ee with retention of stereochemistry.
