Check Digit Verification of cas no

The CAS Registry Mumber 189701-27-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,7,0 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 189701-27:
(8*1)+(7*8)+(6*9)+(5*7)+(4*0)+(3*1)+(2*2)+(1*7)=167
167 % 10 = 7
So 189701-27-7 is a valid CAS Registry Number.

An aluminum porphyrin complex with high activity and selectivity for cyclic carbonate synthesis

Qin, Yusheng,Guo, Hongchen,Sheng, Xingfeng,Wang, Xianhong,Wang, Fosong

, p. 2853 - 2858 (2015/05/27)

An aluminum porphyrin complex with a quaternary ammonium salt cocatalyst exhibits high activity (i.e., a turnover frequency as high as 1.85 × 105 h-1) and selectivity (>99%) for cyclic carbonates synthesis from CO2 and epoxides; the catalyst can be reused at least 4 times with only a slight loss in activity.
