Check Digit Verification of cas no

The CAS Registry Mumber 1401669-95-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,1,6,6 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1401669-95:
(9*1)+(8*4)+(7*0)+(6*1)+(5*6)+(4*6)+(3*9)+(2*9)+(1*5)=151
151 % 10 = 1
So 1401669-95-1 is a valid CAS Registry Number.

PEG-mediated catalyst-free expeditious synthesis of polysubstituted anilines and benzenes via the reaction of malononitrile and β-ketoester derivatives in the presence of activated acetylenes

Piltan, Mohammad,Moradi, Loghman,Salimi, Hiwa,Zargoosh, Kiomars,Zarei, Seyed Amir

, p. 571 - 575 (2012)

Poly(ethylene glycol) (PEG) has been used as a sustainable, non-volatile, and environmentally friendly reaction solvent for synthesis of functionalized anilines and benzenes via the reaction of malononitrile and β-ketoester derivatives in the presence of activated acetylenes at 80o C. No additional solvent and catalyst are required.
