Check Digit Verification of cas no

The CAS Registry Mumber 1416985-07-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,6,9,8 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1416985-07:
(9*1)+(8*4)+(7*1)+(6*6)+(5*9)+(4*8)+(3*5)+(2*0)+(1*7)=183
183 % 10 = 3
So 1416985-07-3 is a valid CAS Registry Number.

A diastereoselective synthesis of pyrano fused coumarins via organocatalytic three-component reaction

Ahadi, Somayeh,Zolghadr, Mahdi,Khavasi, Hamid Reza,Bazgir, Ayoob

, p. 279 - 286 (2013/02/23)

A new method for the synthesis of pyran fused coumarins by 3-bromo-4-hydroxycoumarins as cyclic α-halo ketones based on an organocatalyst assisted three-component tandem reaction is investigated. To the best of our knowledge, cyclic α-halo ketones have not yet been used for the synthesis of pyran fused coumarins.
