Check Digit Verification of cas no
The CAS Registry Mumber 19616-52-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,1 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 19616-52:
(7*1)+(6*9)+(5*6)+(4*1)+(3*6)+(2*5)+(1*2)=125
125 % 10 = 5
So 19616-52-5 is a valid CAS Registry Number.

Studies toward the synthesis of cinachyramine. An efficient route to 1,5-diazabicyclo[4.4.0]dec-5-enes Dedicated to the memory of Professor Harry H. Wasserman

Hydrogenation (3 atm) of readily available pyrido[1,2-a]pyrimidines 10, 14, and 17 over 5% Rh/Al2O3 forms 1,5-diazabicyclo[4.4.0]dec-5-enes 9, 15, and 18 in >95% yield, providing a general route to this little-studied class of compounds. All attempts to form the tetrahydro-1,2,4-triazine moiety of cinachyramine (1) by rearrangement of amidinium dimethylhydrazone 8 using the procedures developed by Kamatori to convert hydrazone 3a to tetrahydro-1,2,4-triazine 4a were unsuccessful.
