Check Digit Verification of cas no

The CAS Registry Mumber 2689-69-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,8 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2689-69:
(6*2)+(5*6)+(4*8)+(3*9)+(2*6)+(1*9)=122
122 % 10 = 2
So 2689-69-2 is a valid CAS Registry Number.

Frutos, Rogelio P.,Tampone, Thomas G.,Mulder, Jason A.,Rodriguez, Sonia,Yee, Nathan K.,Yang, Bing-Shiou,Senanayake, Chris H.

, p. 982 - 988 (2016/06/09)

A practical, safe, and efficient process for the synthesis of PDE4 (phosphodiesterase type 4) inhibitors represented by 1 and 2 was developed and demonstrated on a multi-kilogram scale. Key aspects of the process include the regioselective synthesis of dihydrothieno[3,2-d]pyrimidine-2,4-diol 9 and the asymmetric sulfur oxidation of intermediate 11.
