Check Digit Verification of cas no

The CAS Registry Mumber 1567688-04-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,7,6,8 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1567688-04:
(9*1)+(8*5)+(7*6)+(6*7)+(5*6)+(4*8)+(3*8)+(2*0)+(1*4)=223
223 % 10 = 3
So 1567688-04-3 is a valid CAS Registry Number.

Synthesis of novel polyhydroxylated pyrrolidine-triazole/-isoxazole hybrid molecules

Lin, Cheng-Kun,Cheng, Li-Wei,Li, Huang-Yi,Yun, Wen-Yi,Cheng, Wei-Chieh

, p. 2100 - 2107 (2015)

A straightforward synthesis of novel, 2-heterocyclyl polyhydroxylated pyrrolidines is described. Stereocontrolled additions of nucleophiles to cyclic nitrones generated the corresponding 2,3-trans adducts, allowing the synthesis of the corresponding pyrrolidines via key intermediates bearing an alkyne and a nitrile oxide. Three hybrid systems, including a pyrrolidine with two isoxazoles and one triazole, are efficiently prepared via 1,3-dipolar cycloaddition. Biological testing of the product alkaloids showed that subtle structural variations have drastic effects on their inhibitory activities against glucosidases. This journal is
