Check Digit Verification of cas no

The CAS Registry Mumber 28683-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,8 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28683-81:
(7*2)+(6*8)+(5*6)+(4*8)+(3*3)+(2*8)+(1*1)=150
150 % 10 = 0
So 28683-81-0 is a valid CAS Registry Number.

Y(OTf)3-catalyzed heterocyclic formation via aerobic oxygenation: An approach to dihydro quinazolinones and quinazolinones

Shang, Ying-Hui,Fan, Li-Yan,Li, Xiang-Xiong,Liu, Meng-Xia

supporting information, p. 1355 - 1358 (2015/10/28)

The Y(OTf)3-catalyzed aerobic oxidative cyclization reaction for the selective synthesis of dihydroquinazolinones and quinazolinones has been developed. This method provides a practical, effective and green synthetic approach to dihydroquinazolinones and quinazolinones which both are important units in many biologically active compounds.
