Check Digit Verification of cas no

The CAS Registry Mumber 1233190-41-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,1,9 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1233190-41:
(9*1)+(8*2)+(7*3)+(6*3)+(5*1)+(4*9)+(3*0)+(2*4)+(1*1)=114
114 % 10 = 4
So 1233190-41-4 is a valid CAS Registry Number.

Synthesis of imides and amides from diacetyl-l-tartaric acid anhydride

Naz, Sara,Zaidi, Javid H.,Mehmood, Tahir,Wali, Sher,Ali, Muhammad,Taha, Muhammad,Khan, Khalid M.

experimental part, p. 319 - 322 (2011/07/07)

Diacetyl-L-tartaric acid anhydride reacted with aromatic primary amines to yield imides (3g-l) and amides (4a- f). The ortho-substituted aromatic primary amines either with electron donating or withdrawing groups yielded amides, whereas para-substituted amines produced imides. However, meta-substituted aromatic primary amines with electron withdrawing residues afforded amides while electron donating counterparts furnished imides.
