313974-20-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 313974-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,3,9,7 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 313974-20:
(8*3)+(7*1)+(6*3)+(5*9)+(4*7)+(3*4)+(2*2)+(1*0)=138
138 % 10 = 8
So 313974-20-8 is a valid CAS Registry Number.

, p. 89 - 99 (2007/10/03)
The reaction of iminotriaryl-λ5-bismuthanes (2; Ar3Bi=NR; R = COR″ or SO2R″) with dialkyl acetylenedicarboxylates (3; R′O2CC≡CCO2R′) has been found to afford highly stabilized bismuthonium ylides (4;
