Check Digit Verification of cas no

The CAS Registry Mumber 1421859-20-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,8,5 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1421859-20:
(9*1)+(8*4)+(7*2)+(6*1)+(5*8)+(4*5)+(3*9)+(2*2)+(1*0)=152
152 % 10 = 2
So 1421859-20-2 is a valid CAS Registry Number.

Synthesis and characterization of molecules containing thiazole and oxazole moieties and study of ESIPT phenomenon

Satam, Manjaree A.,Raut, Rajesh K.,Tathe, Abhinav B.,Sekar

, p. 1237 - 1248 (2012)

Two novel ESIPT molecules, 2-[4-(1,3-benzothiazol-2-yl)naphtho[1,2-d][1,3] oxazol-2-yl]phenol 9a and 4-[4-(1,3-benzothiazol-2-yl)naphtho[1,2-d][1,3]oxazol- 2-yl]benzene-1,3-diol 9b were synthesized by condensing 1-amino-3-(1,3- benzothiazol-2-yl)naphthale
