135247-46-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 135247-46-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,2,4 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 135247-46:
(8*1)+(7*3)+(6*5)+(5*2)+(4*4)+(3*7)+(2*4)+(1*6)=120
120 % 10 = 0
So 135247-46-0 is a valid CAS Registry Number.

Characterization of steroidal glycosides from Tylophora sylvatica

Gnabre,Pinnas,Martin,Mizsak,Kloosterman,Baczynskyj,Nielsen,Bates,Hoffmann,Kane

, p. 3545 - 3554 (1991)

Two new steroidal glycosides (tylophoroside 1 and its monoacetate acetyltylophoroside 2) from Tylophora sylvatica (Asclepiadaceae), a medicinal plant from the Ivory Coast, were characterized, largely by 2-D NMR methods. 1, C48H72O22, was found to have three sugars units connected by a vinyl ether linkage to the 3-position of a steroidal aglycone (a new feature in a natural product). The aglycone part contains a novel lactone ring attached at C-13, formed in nature after opening of the D-ring at the 14-15 bond. 1 and 2 have cardiotonic activity, and the aglycone tylogenin 3 if more active than the widely used dexamethasone in anti-allergic assays.
