Check Digit Verification of cas no

The CAS Registry Mumber 714974-24-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,4,9,7 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 714974-24:
(8*7)+(7*1)+(6*4)+(5*9)+(4*7)+(3*4)+(2*2)+(1*4)=180
180 % 10 = 0
So 714974-24-0 is a valid CAS Registry Number.

Matrix presented. The total synthesis of borrelidin has been achieved. The best feature of our synthetic route is Sml2-mediated intramolecular Reformatsky-type reaction for macrocyclization after esterification between two segments. The two key segments were synthesized through chelation-controlled carbotitanation, chelation-controlled hydrogenation, stereoselective Reformatsky reaction, and MgBr2·Et2O-mediated chelation-controlled allylation.

(Chemical Equation Presented) The total synthesis of borrelidin has been achieved. The best feature of our synthetic route is macrocyclization at C11-C12 for the construction of an 18-membered ring after esterification between two segments. A detailed examination of the macrocyclization led us to the samarium(II) iodide-mediated intramolecular Reformatsky-type reaction as the most efficient synthetic approach. The two key segments were synthesized through regioselective methylation, directed hydrogenation, stereoselective Reformatsky-type reaction, and MgBr2·Et2O-mediated chelation-controlled allylation.
