Check Digit Verification of cas no

The CAS Registry Mumber 17105-65-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,1,0 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 17105-65:
(7*1)+(6*7)+(5*1)+(4*0)+(3*5)+(2*6)+(1*5)=86
86 % 10 = 6
So 17105-65-6 is a valid CAS Registry Number.

Synthesis of α-Aryldiazophosphonates via a Diazo Transfer Reaction

Beletskaya, Irina P.,Titanyuk, Igor D.

, p. 2748 - 2757 (2022/03/14)

The simple synthetic procedure for preparation of α-aryl-α-diazophosphonates via a diazo transfer reaction is proposed. Benzylphosphonates reacted with tosyl azide (TsN3) in the presence of potassium tert-butoxide (KOtBu) to afford diazophosphonates in a yield up to 79%. The proposed method is general. The reaction uses easily available starting materials, tolerates various functional groups, and may be applied for multi-gram scale synthesis.
