Check Digit Verification of cas no

The CAS Registry Mumber 13615-11-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,1 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13615-11:
(7*1)+(6*3)+(5*6)+(4*1)+(3*5)+(2*1)+(1*1)=77
77 % 10 = 7
So 13615-11-7 is a valid CAS Registry Number.

A trihomoabietane diterpenoid from Plectranthus grandidentatus and an unusual addition of acetone to the ortho-quinone system of cryptotanshinone

Gaspar-Marques, Cristina,Simoes, M. Fatima,Rodriguez, Benjamin

, p. 1408 - 1411 (2005)

A new 9α-(2-oxopropyl)abietane derivative (1) has been isolated from an acetone extract of Plectranthus grandidentatus. Extraction of the plant material and analytical processes carried out in the absence of acetone also revealed the presence of 1 in the plant, thus suggesting that it is a natural product rather than an artifact. Attempts at obtaining Michael adducts between acetone and para-quinone abietane diterpenoids were unsuccessful, whereas treatment of the ortho-quinone cryptotanshinone (3) with acetone under basic conditions yielded compound 2. The structures of 1 and 2 were established by ID and 2D NMR spectroscopic studies.
