Check Digit Verification of cas no

The CAS Registry Mumber 1348705-17-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,8,7,0 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1348705-17:
(9*1)+(8*3)+(7*4)+(6*8)+(5*7)+(4*0)+(3*5)+(2*1)+(1*7)=168
168 % 10 = 8
So 1348705-17-8 is a valid CAS Registry Number.

1,3-Dipolar cycloaddition of diazoalkanes onto dimethyl 1-(formylamino)ethylenephosphonate: A new route to 1-aminocyclopropanephosphonic acids and 3-phosphorylated pyrazoles

Goulioukina, Nataliya S.,Makukhin, Nikolay N.,Beletskaya, Irina P.

, p. 9535 - 9540 (2011)

Diazoalkanes regiospecifically react with dimethyl 1-(formylamino) ethylenephosphonate (1a) to afford 5-substituted dimethyl 3-(formylamino)-4,5- dihydro-3H-pyrazol-3-phosphonates 2 in high yields. Their thermal decomposition followed by hydrolysis provid
