92139-38-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92139-38-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,3 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 92139-38:
(7*9)+(6*2)+(5*1)+(4*3)+(3*9)+(2*3)+(1*8)=133
133 % 10 = 3
So 92139-38-3 is a valid CAS Registry Number.

, p. 1345 - 1348 (2007/10/02)
Tetraphenyl-, tetraethyl-, and 1,1-diphenyl-2,3-diethylphosphirenium cations can be prepared by extension of a previously desribed procedure, but base-promoted cyclizations of 1,3-dihalophosphonium cations proceed to ring-opened products by an alternate p
