Check Digit Verification of cas no

The CAS Registry Mumber 1017242-01-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,7,2,4 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1017242-01:
(9*1)+(8*0)+(7*1)+(6*7)+(5*2)+(4*4)+(3*2)+(2*0)+(1*1)=91
91 % 10 = 1
So 1017242-01-1 is a valid CAS Registry Number.

Tetraarylphosphonium-supported carbodiimide reagents: Synthesis, structure optimization and applications

Ginisty, Maryon,Roy, Marie-Noelle,Charette, Andre B.

, p. 2542 - 2547 (2008/09/19)

(Chemical Equation Presented) New tetraarylphosphonium (TAP)-supported alkyl- and arylcarbodiimides were synthesized and used as coupling reagents for esterification reactions, amidation reactions and dehydration reactions of hydroxyesters. Taking advantage of the solubility properties imparted by the tetraarylphosphonium unit, a simple precipitation and filtration allowed complete separation of the urea by-products. This paper describes the structure optimization study of the various TAP-supported carbodiimide reagents to obtain the desired reactivity and solubility profile. Furthermore, we have demonstrated that the diimide reagent can be regenerated from the urea to recycle the reagents.
