Check Digit Verification of cas no

The CAS Registry Mumber 191598-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,5,9 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 191598-01:
(8*1)+(7*9)+(6*1)+(5*5)+(4*9)+(3*8)+(2*0)+(1*1)=163
163 % 10 = 3
So 191598-01-3 is a valid CAS Registry Number.

( Z)-1-Methoxy-4-( diphenylphosphino) but-1-ene-3-yne: A versatile synthon for unsymmetrically substituted ( diphenylphosphino) diacetylene derivatives

Corriu, Robert J.P.,Guerin, Christian,Henner, Bernard J.L.,Jolivet, Agnes

, p. 39 - 48 (2007/10/03)

An efficient synthesis of Ph2P-C≡C-C≡C-Li, 1, was found, starting from commercially available (Z)-1-methoxybut-1-ene-3-yne and its diphenylphosphino derivative 2. The lithio compound 1 was condensed with electrophiles to give Ph2P-C≡
