Check Digit Verification of cas no

The CAS Registry Mumber 219501-22-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,5,0 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 219501-22:
(8*2)+(7*1)+(6*9)+(5*5)+(4*0)+(3*1)+(2*2)+(1*2)=111
111 % 10 = 1
So 219501-22-1 is a valid CAS Registry Number.

Hypervalent iodine in synthesis 80: One pot preparation of Se-(β-oxoalkyl) O,O-dialkyl selenophospates by reaction of ketones, [hydroxy(tosyloxy)iodo]benzene, and potassium O,O-dialkyl selenophosphates

Xie,Chen

, p. 156 - 157 (2007/10/03)

One pot reactions of ketones, [hydroxy(tosyloxy)iodo]benzene and potassium O,O-dialkyl selenophosphates lead to the formation of the corresponding Se-(β-oxoalkyl)O,O-dialkyl selenophosphates under mild conditions and in good yield.
