Check Digit Verification of cas no

The CAS Registry Mumber 127613-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,1 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127613-71:
(8*1)+(7*2)+(6*7)+(5*6)+(4*1)+(3*3)+(2*7)+(1*1)=122
122 % 10 = 2
So 127613-71-2 is a valid CAS Registry Number.

STEREOSELECTIVE SYNTHESIS OF THE AROMATIC ANALOGS OF RETINAL AND RETONOIC ACID

Makin, S. M.,Mikerin, I. E.,Shavrygina, O. A.,Lanina, T. I.

, p. 710 - 715 (2007/10/02)

The stereoselective synthesis of 9-aryl-4-carboxy-3,7-dimethyl-2Z,4Z,6E,8E-nonatetraenoic acids and 9-aryl-3,7-dimethyl-2Z,4E,6E,8E-nonatetraenoic acids was realized.The latter isomerize readily and with good yields under the influence of iodine additions to 9-aryl-3,7-dimethyl-2E,4E,6E,8E-nonatetraenoic acids.The transition from the isomeric 9-aryl-3,7-dimethyl-2,4,6,8-nonatetraenoic acids to the corresponding isomeric 9-aryl-3,7-dimethyl-2Z,4E,6E,8E-nonatetraenals and 9-aryl-3,7-dimethyl-2E,4E,6E,8E-nonatetraenals was realized.
