138122-98-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138122-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,1,2 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138122-98:
(8*1)+(7*3)+(6*8)+(5*1)+(4*2)+(3*2)+(2*9)+(1*8)=122
122 % 10 = 2
So 138122-98-2 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.
