The structure also includes a seco-strychnidine framework, which means it has undergone a ring-opening reaction at the 16,19 positions, and contains two carbonyl groups at the 10th and 16th positions. 11-((Ξ)-benzylidene)-4-hydroxy-19-methyl-16,19-seco-strychnidine-10,16-dione is of interest in the field of organic chemistry and pharmacology due to its potential biological activities and structural complexity.
The CAS Registry Mumber 1329-61-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 9 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1329-61: (6*1)+(5*3)+(4*2)+(3*9)+(2*6)+(1*1)=69 69 % 10 = 9 So 1329-61-9 is a valid CAS Registry Number.
