138971-42-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138971-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,7 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138971-42:
(8*1)+(7*3)+(6*8)+(5*9)+(4*7)+(3*1)+(2*4)+(1*2)=163
163 % 10 = 3
So 138971-42-3 is a valid CAS Registry Number.

Generation and trapping of the pseudo-diatomic "R.P=S"

Folkins, Patricia L.,Vincent, Beverly R.,Harpp, David N.

, p. 7009 - 7012 (2007/10/02)

The generation of a pseudo-diatomic species "R.P=S" (thioxophosphane) has been achieved from the reaction of triphenyldibromophosphorane (4) with bis(triphenylmethylmercapto)phosphines (7). This reactive intermediate was trapped via Diels-Alder addition to 1,3-dienes producing cyclic thiophosphoranes 13, 15, 16 and 18 along with two acyclic species, 14 and 17.
