General Description
The chemical "(1R,3aR,4S,4aR,7R,7aR,8aS)-4-formyl-7-methyl-8a-({[(3aR,5R,7R,7aS)-7-methyl-3-methylidenehexahydro-2H-furo[2,3-c]pyran-5-yl]oxy}methyl)-3-(propan-2-yl)-4,4a,5,6,7,7a,8,8a-octahydro-1,4-methano-s-indacene-3a(1H)-carboxylic acid" is a complex organic compound with a long, intricate molecular structure. It contains carbonyl, methyl, and carboxylic acid functional groups, and its structure includes a cyclohexane-fused oxepane ring and a bicyclic s-indacene ring system. The compound's stereochemistry is defined by multiple asymmetric carbon centers, and its synthesis and properties likely involve a high degree of chemical complexity and specificity.
Check Digit Verification of cas no
The CAS Registry Mumber 199013-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,0,1 and 3 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 199013-04:
(8*1)+(7*9)+(6*9)+(5*0)+(4*1)+(3*3)+(2*0)+(1*4)=142
142 % 10 = 2
So 199013-04-2 is a valid CAS Registry Number.
