Check Digit Verification of cas no
The CAS Registry Mumber 131527-02-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,5,2 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 131527-02:
(8*1)+(7*3)+(6*1)+(5*5)+(4*2)+(3*7)+(2*0)+(1*2)=91
91 % 10 = 1
So 131527-02-1 is a valid CAS Registry Number.

SYNTHESIS OF 11,12,12a,13-TETRAHYDRO-6H-INDOLOBENZODIAZEPINES
Shachkus, A. A.,Degutis, Yu. A.,Myadyakshene, G. S.
, p. 681 - 682 (2007/10/02)
Alkylation of 2,3,3-trimethyl- and 2,3,3,5-tetramethyl-3H-indoles with 2-bromomethylbenzonitrile gave 2-methylene-1-(2-cyanobenzyl)-2,3-dihydro-1H-indoles.When reacted with lithium aluminum hydride the latter are cyclized to 11,12,12a,13-tetrahydro-6H-indolobenzodiazepines.
