124015-83-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124015-83-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,0,1 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 124015-83:
(8*1)+(7*2)+(6*4)+(5*0)+(4*1)+(3*5)+(2*8)+(1*3)=84
84 % 10 = 4
So 124015-83-4 is a valid CAS Registry Number.

REGIOSELECTIVE ALKYLATION OF DIANIONS OF CYCLIC 1,3-DIKETONES VIA THEIR MONODIMETHYLHYDRAZONES. SYNTHESIS OF C-4 SUBSTITUTED 1,3-DIKETONES
Demir, Ayhan S.,Enders, Dieter
