Check Digit Verification of cas no

The CAS Registry Mumber 185913-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,9,1 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 185913-28:
(8*1)+(7*8)+(6*5)+(5*9)+(4*1)+(3*3)+(2*2)+(1*8)=164
164 % 10 = 4
So 185913-28-4 is a valid CAS Registry Number.

Foiling Normal Patterns of Crystallization by Design. Polymorphism of Phosphangulene Chalcogenides

Heskia, Alice,Maris, Thierry,Wuest, James D.

, p. 5390 - 5406 (2019/09/12)

Phosphangulene (1) has a well-defined hexacyclic structure with a distinctive conical shape and an electron-rich aromatic surface. Molecules of phosphangulene are disposed to crystallize in parallel π-stacks. This preference can be thwarted by adding a si
