Check Digit Verification of cas no

The CAS Registry Mumber 197218-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,2,1 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 197218-69:
(8*1)+(7*9)+(6*7)+(5*2)+(4*1)+(3*8)+(2*6)+(1*9)=172
172 % 10 = 2
So 197218-69-2 is a valid CAS Registry Number.

Chemistry of allene sulfoxides: A new synthesis of 1-aryl-3,4-dihydro-1H-[1]benzothieno[3,2-c]pyrans

Edwards, Neil,Macritchie, Jacqueline A.,Parsons, Philip J.,Drew, Michael G. B.,Jahans, Archie W.

, p. 12651 - 12660 (2007/10/03)

A novel synthesis of 1-aryl-3,4-dihydro-1H-[1]benzothieno[3,2-c]pyrans has been developed. utilising the acid-catalysed cyclisation of 5,6-dihydro-4-phenylsulfinyl-2H-pyrans. Both ring systems could be isolated from suitably substituted allene sulfoxides
