139210-87-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139210-87-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,1 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139210-87:
(8*1)+(7*3)+(6*9)+(5*2)+(4*1)+(3*0)+(2*8)+(1*7)=120
120 % 10 = 0
So 139210-87-0 is a valid CAS Registry Number.

Formation and efficient addition of cerium(III) derivative of acetonitrile to ketones
Liu,Al-Said
, p. 5473 - 5476 (2007/10/02)
The cerium(III) derivative of acetonitrile undergoes addition with ketones efficiently. It adds effectively to hindered ketones and gives 1,2-adduct exclusively with conjugated enones.
