Check Digit Verification of cas no
The CAS Registry Mumber 103184-59-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,1,8 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 103184-59:
(8*1)+(7*0)+(6*3)+(5*1)+(4*8)+(3*4)+(2*5)+(1*9)=94
94 % 10 = 4
So 103184-59-4 is a valid CAS Registry Number.

CHEMISTRY OF METALLO-KETENE-S,N-ACETALS. NEW SYNTHESIS OF AZACYCLOALKAPYRIMIDINES
Takahata, Hiroki,Suzuki, Toshiaki,Yamazaki, Takao
, p. 2213 - 2215 (2007/10/02)
Bis-lithio-ketene-S,N-acetals, generated from thiolactams by treatment with n-BuLi, react with aryl isothiocyanates to give dithioamides.Bismethylation of the dithioamides followed by condensation with benzamidine affords the azacycloalkapyrimidines.
