Check Digit Verification of cas no
The CAS Registry Mumber 158874-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,8,7 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 158874-98:
(8*1)+(7*5)+(6*8)+(5*8)+(4*7)+(3*4)+(2*9)+(1*8)=197
197 % 10 = 7
So 158874-98-7 is a valid CAS Registry Number.

SYNTHESIS AND REACTIVITY OF A NEW 1,1-DIPHENYL 2,5-DIHYDROPHOSPHOLIUM SALT
Cristau, H.-J.,Grenier, J.,Torreilles, E.
, p. 163 - 172 (2007/10/02)
We describe the first synthesis of an unsaturated cyclic diphenyl phosphoium salt of type 2, the 1,1-diphenyl 2,5-dihydrophospholium salt 2d.The method involves a cyclo-addition of the diphenyl halophosphine to the corresponding diene.The salt 2d allowed
