Check Digit Verification of cas no
The CAS Registry Mumber 591752-34-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,9,1,7,5 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 591752-34:
(8*5)+(7*9)+(6*1)+(5*7)+(4*5)+(3*2)+(2*3)+(1*4)=180
180 % 10 = 0
So 591752-34-0 is a valid CAS Registry Number.

A novel substitution reaction of tetrahydropyrano[3,4-b]indole derivative - Chain extension and structural correlation study
Chou, Shan-Yen
, p. 1095 - 1110 (2003)
An unusual cyanation with rearrangement of a 1-chloromethyl-tetrahydropyrano[3,4-b]indole-1-acetic acid ester derivative is reported. The resulting C-1 chain extension product is identified by correlation studies and spectral method.
