138713-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138713-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,1 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138713-12:
(8*1)+(7*3)+(6*8)+(5*7)+(4*1)+(3*3)+(2*1)+(1*2)=129
129 % 10 = 9
So 138713-12-9 is a valid CAS Registry Number.

, p. 6563 - 6566 (2007/10/02)
1-Arylalkenyl sulfides were produced in good yields by treatment of 1-(phenylthio)vinyl chlorides with arenes in the presence of aluminum chloride or ethylaluminum dichloride. The stereoselectivity indicated that the reaction is a kinetically controlled p
