Check Digit Verification of cas no

The CAS Registry Mumber 111604-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,6,0 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111604-99:
(8*1)+(7*1)+(6*1)+(5*6)+(4*0)+(3*4)+(2*9)+(1*9)=90
90 % 10 = 0
So 111604-99-0 is a valid CAS Registry Number.

Fluoride-catalyzed Michael addition of nitrotoluenes to activated α, β-unsaturated esters

Li, Wen-Sen,Thottathil, John,Murphy, Michael

, p. 6591 - 6594 (2007/10/02)

We have found that in the presence of fluoride ion, nitrotoluenes of type 1 undergo Michael addition to activated α, β-unsaturated esters of type 2 in good to excellent yield (Scheme 1). The generality and limitation of this reaction and its application t

Benzazepinone calcium channel blockers. 2. Structure-activity and drug metabolism studies leading to potent antihypertensive agents. Comparison with benzothiazepinones

, p. 756 - 772 (2007/10/02)

As part of a program to discover potent antihypertensive analogues of diltiazem (3a), we prepared 1-benzazepin-2-ones (4). Benzazepinones competitively displace radiolabeled diltiazem, and show the same absolute stereochemical preferences at the calcium channel receptor protein. Derivatives of 4 containing a trifluoromethyl substituent in the fused aromatic ring show potent and long-acting antihypertensive activity. Studies of the metabolism of 4 lead to the metabolically stable antihypertensive calcium channel blockers 5a and 5c. Benzazepinone 5a is a longer acting and more potent antihypertensive agent than the second generation diltiazem analogue TA-3090 (3e).
