Check Digit Verification of cas no

The CAS Registry Mumber 88390-01-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,3,9 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 88390-01:
(7*8)+(6*8)+(5*3)+(4*9)+(3*0)+(2*0)+(1*1)=156
156 % 10 = 6
So 88390-01-6 is a valid CAS Registry Number.

Reactions with Betaines, XXIII. Reactions of Nitrogen- and Sulphur-Betaines with Reactive Halides

Wittmann, Helga,Ziegler, Erich

, p. 103 - 112 (2007/10/02)

Trimethylammonium acetic betain (1) reacts with phenacyl bromide and ethyl bromoacetate, respectively, to give the ester bromides 2 and 7.These can be hydrolyzed with aqueous sodium hydrogencarbonate at 20 deg C to yield besides 1 both C-benzoyl-methanol (3) and the glycolic acid ester 8, respectively.The reaction can also be performed in one step by reacting the betain (1) (with can act as a base) in a double molar ratio with the active halide. - Keywords: Trimethylammonium acetic acid betain; Trimethylammonium acetic acid phenacyl ester bromide; Trimethylammonium acetic acid acetoxy ethyl ester bromide; Phenacyl alcohol; Ethyl glycolate
