139224-25-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139224-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,2 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139224-25:
(8*1)+(7*3)+(6*9)+(5*2)+(4*2)+(3*4)+(2*2)+(1*5)=122
122 % 10 = 2
So 139224-25-2 is a valid CAS Registry Number.

Kodomari, Mitsuo,Saitoh, Goroh,Yoshitomi, Suehiko
, p. 3485 - 3487 (2007/10/02)
The addition of thiols to methyl propiolate was remarkably accelerated in the presence of alumina to give the Z-isomer of the 1:1 adducts stereoselectively, in which alumina acts as a bifunctional catalyst of acid and base.
