74291-50-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74291-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,9 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74291-50:
(7*7)+(6*4)+(5*2)+(4*9)+(3*1)+(2*5)+(1*0)=132
132 % 10 = 2
So 74291-50-2 is a valid CAS Registry Number.

Inhibitors of phenylethanolamine N-methyltransferase and epinephrine biosynthesis. 2. 1,2,3,4-Tetrahydroisoquinoline-7-sulfonanilides.

Blank,Krog,Weiner,Pendleton

, p. 837 - 840 (2007/10/02)

1,2,3,4-Tetrahydroisoquinoline-7-sulfonanilides (1-14) related to 1,2,3,4-tetrahydroisoquinoline-7-sulfonamide (21,SK&F 29661) were prepared and studied for their ability to inhibit phenylethanolamine N-methyltransferase (PNMT) in vitro. The choice of substituents on the 7-phenyl group of the sulfonanilides was based on the Topliss approach to structure-activity relationship studies. Information about the importance of an acidic hydrogen atom on the sulfonamide nitrogen atom was obtained from the preparation and testing of a tertiary N-methylsulfonanilide (15). Other THIQ's (1,2,3,4-tetrahydroisoquinolines) containing sulfur substituents in the 7 position were prepared and tested and consisted of 7-N-benzyl and 7-N-phenethyl derivatives of SK&F 29661 (16-18) and 7-(phenacylthio)-and 7-(phenacylsulfonyl)-THIQ (19 and 20). The two most potent inhibitors were the 7-p-bromo- and -chlorosulfonanilides, 2 and 6. However, neither was an effective inhibitor of norepinephrine to epinephrine conversion when tested in an in vivo mouse assay at unit doses of 25 or 100 mg/kg.
