13225-60-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13225-60-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,2 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13225-60:
(7*1)+(6*3)+(5*2)+(4*2)+(3*5)+(2*6)+(1*0)=70
70 % 10 = 0
So 13225-60-0 is a valid CAS Registry Number.

Direct conversion of dipropargylic sulfones into (E)- and (Z)-Hex-3-ene-1,5-diynes by a modified one-flask Ramberg-Backlund reaction
Cao,Chan,Chow
, p. 1049 - 1052 (1996)
(E)- and (Z)-enediynes 7 are readily synthesized in good yields from a one-pot modified Ramberg-Backlund reaction from dipropargylic sulfones 5.
