Check Digit Verification of cas no

The CAS Registry Mumber 205812-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,8,1 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 205812-80:
(8*2)+(7*0)+(6*5)+(5*8)+(4*1)+(3*2)+(2*8)+(1*0)=112
112 % 10 = 2
So 205812-80-2 is a valid CAS Registry Number.

An efficient synthesis of peri-hydroxy aromatic compounds: A strong base-induced [4+2]cycloaddition of 4-phenylthio-substituted homophthalic anhydrides with various sulfinyl-substituted dienophiles

, p. 292 - 294 (1998)

As an extension of the strong base-induced [4+2]cycloaddition of homophthalic anhydrides studied previously, we found a general and versatile synthesis of p-phenylthio substituted phenols by the reaction of 4-phenylthio-substituted homophthalic anhydrides and various dienophiles. The use of the sulfinyl-substituted dienophile is essential to produce the desired reaction under mild conditions in good yield.
