Check Digit Verification of cas no

The CAS Registry Mumber 200069-26-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,0,6 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 200069-26:
(8*2)+(7*0)+(6*0)+(5*0)+(4*6)+(3*9)+(2*2)+(1*6)=77
77 % 10 = 7
So 200069-26-7 is a valid CAS Registry Number.

Competitive [4+2] cycloadditions in equimolar mixtures of 1-arylphosphole oxides

Keglevich,Chuluunbaatar,Dajka,Namkhainyambuu,Ludanyi,Toke

, p. 633 - 635 (2001)

Four different [4+2] cycloadditions were observed to take place in the equimolar mixtures of two different arylphosphole oxides 2a + 2b or 2b + 2c. In addition to the phosphole oxide dimers 3a-a and 3b-b, or 3b-b and 3c-c, the crossed cycloadducts 3a-b and 3b-a, or 3b-c and 3c-b were also formed in considerable portions.
