131302-79-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131302-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,0 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131302-79:
(8*1)+(7*3)+(6*1)+(5*3)+(4*0)+(3*2)+(2*7)+(1*9)=79
79 % 10 = 9
So 131302-79-9 is a valid CAS Registry Number.

PHOTOLYSIS OF DIPHOSPHONATE DERIVATIVES HAVING AROMATIC RING ASSEMBLIES
Shi, Min,Okamoto, Yoshiki,Takamuku, Setsuo
, p. 101 - 107 (2007/10/02)
Upon UV-irradiation in methanol the diphosphonates fully substituted with aromatic rings give biaryls and aryl(dimethoxy)carbene derivatives in quantum yield of 0.01-0.03.The mechanism of the selective α,α-elimination of aryl groups was discussed.
