Check Digit Verification of cas no

The CAS Registry Mumber 195623-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,6,2 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 195623-12:
(8*1)+(7*9)+(6*5)+(5*6)+(4*2)+(3*3)+(2*1)+(1*2)=152
152 % 10 = 2
So 195623-12-2 is a valid CAS Registry Number.

A convenient method for the one-step synthesis of phosphonic peptides

Skoreński, Marcin,Oleksyszyn, Józef,Sieńczyk, Marcin

supporting information, p. 4975 - 4977 (2013/09/02)

A novel and efficient method for the synthesis of peptidyl derivatives of 1-aminoalkylphosphonate diaryl esters is presented. Phosphonic peptides were obtained in one step via an amidoalkylation reaction using amides of N-protected amino acids or peptides, triphenyl phosphite, and an appropriate aldehyde.
