Check Digit Verification of cas no

The CAS Registry Mumber 290817-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,8,1 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 290817-91:
(8*2)+(7*9)+(6*0)+(5*8)+(4*1)+(3*7)+(2*9)+(1*1)=163
163 % 10 = 3
So 290817-91-3 is a valid CAS Registry Number.

Unusual stabilization of 1,2-diamino derivatives of quincorine and quincoridine by carbon dioxide: Persistent crystalline prim-ammonium-carbamate salts and their reactivity towards isatoic acid anhydride

Neda, Ion,Kaukorat, Thomas,Fischer, Axel K.

, p. 3784 - 3790 (2007/10/03)

The reaction of N-methylisatoic anhydride 1 with a series of quincorine (QCI) and quincoridine (QCD) derivatives furnished the corresponding QCI- and QCD-substituted anthranilic acid amides 4-9. In the synthesis of 4-9, we investigated the influence of th
