Check Digit Verification of cas no

The CAS Registry Mumber 137152-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,5 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137152-49:
(8*1)+(7*3)+(6*7)+(5*1)+(4*5)+(3*2)+(2*4)+(1*9)=119
119 % 10 = 9
So 137152-49-9 is a valid CAS Registry Number.

Synthesis of 9-acetyl-8,9-diaza-1-phosphabicyclo[4.3.0]nona-3,7-dienes by regioselective Diels-Alder reaction of 2H-1,2,3-diazaphospholes with isoprene

Chen,Cai,Li

, p. 783 - 784 (1991)

2H-1,2,3-Diazaphospholes, prepared from various hydrazones and phosphorus trichloride in the presence of triethylamine, react with isoprene to give highly regioselective Diels-Alder products in good yield.
