Check Digit Verification of cas no

The CAS Registry Mumber 119308-94-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,3,0 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 119308-94:
(8*1)+(7*1)+(6*9)+(5*3)+(4*0)+(3*8)+(2*9)+(1*4)=130
130 % 10 = 0
So 119308-94-0 is a valid CAS Registry Number.

Two new pyridine monoterpene alkaloids by chemical conversion of a commercial extract of Harpagophytum procumbens

Baghdikian,Ollivier,Faure,Debrauwer,Rathelot,Balansard

, p. 211 - 213 (2007/10/03)

The treatment of harpagide (1), harpagoside (2), or 8-O-p- coumaroylharpagide (3), the main iridoids of Harpagophytum procumbens and Harpagophytum zeyheri, with NH3 and HCl led to aucubinine B(4), a pyridine monoterpene alkaloid (PMTA). A similar procedure applied to a commercial extract of H. procumbens yielded 4 and two new PMTAs named beatrine A (5) and beatrine B (6). The structures of these new PMTAs were established using ESIMS and 2D NMR. Their semisynthesis was analyzed in terms of reaction mechanisms.
