Check Digit Verification of cas no
The CAS Registry Mumber 133488-87-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,8 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133488-87:
(8*1)+(7*3)+(6*3)+(5*4)+(4*8)+(3*8)+(2*8)+(1*7)=146
146 % 10 = 6
So 133488-87-6 is a valid CAS Registry Number.

An Improved Synthesis of 3,6-Diamino-1,2,4,5-tetrazine. I
Coburn, Michael D.,Ott, Donald G.
, p. 1941 - 1945 (2007/10/02)
Treatment of 1,3-diaminoguanidine monohydrochloride (1) with 2,4-pentanedione (2) in alcohols under carefully controlled conditions gave 3,6-diamino-1,2-dihydro-1,2,4,5-tetrazine monohydrochloride (3) in 45-50percent yields along with 3,5-dimethyl-1H-pyrazole (4) and its hydrochloride 5.Oxidation of 3 with sodium perborate produced 3,6-diamino-1,2,4,5-tetrazine (6) in quantitative yield.
