Check Digit Verification of cas no
The CAS Registry Mumber 1301176-78-2 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, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1301176-78:
(9*1)+(8*3)+(7*0)+(6*1)+(5*1)+(4*7)+(3*6)+(2*7)+(1*8)=112

, p. 4529 - 4531 (2011/06/19)
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
