Check Digit Verification of cas no

The CAS Registry Mumber 90745-29-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,4 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90745-29:
(7*9)+(6*0)+(5*7)+(4*4)+(3*5)+(2*2)+(1*9)=142
142 % 10 = 2
So 90745-29-2 is a valid CAS Registry Number.

12-S-CIS CONFORMATIONALLY LOCKED RETINOIDS: THERMAL AND PHOTOCHEMICAL INTERCONVERSIONS LEADING TO NEW GEOMETRIC ISOMERS

Chandraratna, Roshantha A. S.,Okamura, William H.

, p. 1003 - 1006 (1984)

For 12-s-cis locked retinal analogues, thermal equilibria are established between 11-cis,13-cis-1c and 13-cis-2c and between 9-cis,11-cis,13-cis-1d and 9-cis,13-cis-2d; a photoisomerisation occurs to transform 2c to all-trans-2a and 2d to 9-cis-2b.
