31603-06-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31603-06-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,6,0 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 31603-06:
(7*3)+(6*1)+(5*6)+(4*0)+(3*3)+(2*0)+(1*6)=72
72 % 10 = 2
So 31603-06-2 is a valid CAS Registry Number.

Tetrazole analogs of phenylalanine derivatives as tyrosine hydroxylase inhibitors
McNeil,Williams Jr.,Darling
, p. 1642 - 1644 (2007/10/08)
Eight new tetrazole analogs of phenylalanine derivatives in which the carboxyl group was replaced by a tetrazole ring were synthesized. At a concentration of 2.5 x 10-5 M, each compound exhibited greater than 50% inhibition of tyrosine hydroxylase activity.
