1301176-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1301176-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,1,1,7 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1301176-91:
(9*1)+(8*3)+(7*0)+(6*1)+(5*1)+(4*7)+(3*6)+(2*9)+(1*1)=109
109 % 10 = 9
So 1301176-91-9 is a valid CAS Registry Number.

Ring-opening reactions of 2-aryl-3, 4-dihydropyrans with nucleophiles were reported for the first time. A possible mechanism was also proposed. Finally, this method was used in the synthesis of a novel tetrahydrocarbazole derivative that possesses a biolo
