Check Digit Verification of cas no

The CAS Registry Mumber 33238-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,3 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 33238-42:
(7*3)+(6*3)+(5*2)+(4*3)+(3*8)+(2*4)+(1*2)=95
95 % 10 = 5
So 33238-42-5 is a valid CAS Registry Number.

Synthesis of Acyl Phosphoramidates Employing a Modified Staudinger Reaction

Currie, Iain,Sleebs, Brad E.

supporting information, p. 464 - 468 (2021/02/03)

A one-step synthesis of acyl phosphoramidates from a variety of functionalized acyl azides has been developed employing trimethylsilyl chloride as an activating agent in a modified Staudinger reaction. The methodology was further adapted to include the in situ generation of the acyl azides from a diverse selection of carboxylic acids and hydrazide starting synthons. The reaction scope was extended to include the synthesis of imidodiphosphates and the natural product Microcin C.
