Check Digit Verification of cas no

The CAS Registry Mumber 1388045-78-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,8,0,4 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1388045-78:
(9*1)+(8*3)+(7*8)+(6*8)+(5*0)+(4*4)+(3*5)+(2*7)+(1*8)=190
190 % 10 = 0
So 1388045-78-0 is a valid CAS Registry Number.

Syntheses of 4-, 5-, 6-, and 7-substituted tryptamine derivatives and the use of a bromine atom as a protecting group

René, Olivier,Fauber, Benjamin P.

, p. 830 - 833 (2014)

Orthogonal syntheses of 4-, 5-, 6-, and 7-chloro substituted tryptamine derivatives were performed under the Grandberg-Zuyanova-modified Fisher indole-synthesis conditions. In the 4- and 6-substituted tryptamine cases, a bromine atom was utilized as an easily cleavable protecting group, which allowed complete regiocontrol. In addition, a chlorine substituent was preserved in the debromination step and could be utilized as a synthetic handle for late-stage diversification under modern Pd(0) catalysis conditions.
