Check Digit Verification of cas no

The CAS Registry Mumber 15083-15-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,0,8 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 15083-15:
(7*1)+(6*5)+(5*0)+(4*8)+(3*3)+(2*1)+(1*5)=85
85 % 10 = 5
So 15083-15-5 is a valid CAS Registry Number.

Influence of impurities on the crystallisation of 5-X-aspirin and 5-X-aspirin anhydride polymorphs (X = Cl, Br, Me)

Solanko, Katarzyna A.,Bond., Andrew D.

, p. 6991 - 6996 (2011)

Crystallisation of 5-X-aspirin (X = Cl, Br) by ambient evaporation from organic solvents commonly yields a mixture of polymorphs I and II for X = Cl, but only polymorph I for X = Br. Addition of 5-X-aspirin anhydride (5-20 mol %) leads to sole production
