Check Digit Verification of cas no
The CAS Registry Mumber 227804-07-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,8,0 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 227804-07:
(8*2)+(7*2)+(6*7)+(5*8)+(4*0)+(3*4)+(2*0)+(1*7)=131
131 % 10 = 1
So 227804-07-1 is a valid CAS Registry Number.

A new method for the synthesis of medium- and large-sized carbocycles
Masuya, Keiichi,Tanino, Keiji,Kuwajima, Isao
, p. 647 - 649 (1999)
A new synthetic method for medium and large-sized carbocycles has been developed. An acyclic compound having an olefin moiety and a 3- (methylthio)allyl acetate moiety at each of the terminal positions was designed as a cyclization precursor. The correspo
