Check Digit Verification of cas no

The CAS Registry Mumber 81390-27-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,9 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81390-27:
(7*8)+(6*1)+(5*3)+(4*9)+(3*0)+(2*2)+(1*7)=124
124 % 10 = 4
So 81390-27-4 is a valid CAS Registry Number.

Synthesis of Phosphorins by Reaction of 1,2,5-Triphenylphosphole with Alkynes

Charrier, Claude,Bonnard, Hubert,Mathey, Francois

, p. 2376 - 2379 (2007/10/02)

When heated several days at 230 deg C, 1,2,5-triphenylphosphole yields 2,2',3,3',5,5'-hexaphenyl-1,1'-biphospholyl through a transient 2H-phosphole.The reactions of this biphospholyl with lithium, manganese carbonyl, and molybdenum carbonyl are described.
