Check Digit Verification of cas no

The CAS Registry Mumber 1336877-79-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,6,8,7 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1336877-79:
(9*1)+(8*3)+(7*3)+(6*6)+(5*8)+(4*7)+(3*7)+(2*7)+(1*9)=202
202 % 10 = 2
So 1336877-79-2 is a valid CAS Registry Number.

Regioselective synthesis of aurone derivatives via PBu3-catalyzed cyclization of 2-alkynoylphenols

Liu, Changqing,Zhang, Zhannan,Zhang, Jitan,Liu, Xing,Xie, Meihua

, p. 1233 - 1237 (2014)

Aurone derivatives were synthesized in good to high yields by PBu3-catalyzed intramolecular 5-exo cyclization of 2-alkynoylphenols. The reaction proceeds in high regioselectivity without forming 6-endo cyclization products.
