Check Digit Verification of cas no

The CAS Registry Mumber 136491-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,4,9 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136491-99:
(8*1)+(7*3)+(6*6)+(5*4)+(4*9)+(3*1)+(2*9)+(1*9)=151
151 % 10 = 1
So 136491-99-1 is a valid CAS Registry Number.

Cheletropic reactions in diphosphirane series

Etemad-Moghadam,Tachou,Gouygou,Koenig

, p. 3687 - 3690 (1991)

In the diphosphirane series, whereas the fragmentation is a side reaction during the photochemical, thermal or cationic ring opening, the oxidation of the phosphorus lone pairs leads quantitatively to the corresponding phosphaalkenes, and the unstable pho
