Check Digit Verification of cas no

The CAS Registry Mumber 23609-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,6,0 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 23609-90:
(7*2)+(6*3)+(5*6)+(4*0)+(3*9)+(2*9)+(1*0)=107
107 % 10 = 7
So 23609-90-7 is a valid CAS Registry Number.

Syntheses of highly substituted furan and pyrrole derivatives via lithiated 3-aryl-1-methoxyallenes: Application to the synthesis of codonopsinine

Chowdhury, Morshed Alam,Reissig, Hans-Ulrich

, p. 2383 - 2386 (2008/02/09)

Lithiated 1-methoxy-3-phenylallenes were generated in situ from a phenyl-substituted propargylic ether. They smoothly combined with aldehydes, ketones, or imines to give allenyl adducts, which cyclized to highly substituted heterocycles either under basic
